Haines of Burlington County, New Jersey

Ezra Adams (1768-1824) and Hannah Haines (1771-1824) were my fifth great grandparents. Ezra purchased several parcels of land in what is now Hamilton, Mercer County, New Jersey, but was called Nottingham, Burlington County during Ezra's life. Ezra purchased tracts from some of his siblings that were inherited from their father, Alexander Adams. When Ezra died, his seven children inherited partitions of his land. Hannah, widow of Ezra, died four months after him; however, she was not mentioned in his estate papers.

I've been trying to connect Hannah to her parents. Ancestry suggests Jacob Haines and Sarah Austin.

Ancestry proposed parents: Jacob Haines and Sarah Austin.

Jacob Haines and Sarah Austin were Quakers. They were disowned, thereby falling off the extensive record-keeping.

People researched and wrote about the Haines of Burlington County. Jacob Haines and Sarah Austin had a daughter named Hannah Haines, but her birthdate was around 1787, which is later than my ancestor Hannah. Plus, this Hannah married Jonathan Austin, not Ezra Adams.

Excerpt of family history book by John Wesley Haines

I'm not writing that these books about Haines are correct about Hannah, but these are the records that Ancestry is citing for support that Hannah Haines, daughter of Jacob Haines and Sarah Austin, married Ezra Adams. People attached these records into their trees in support of the union of Hannah Haines and Ezra Adams, even though these records contradict this claim.

Jacob Haines' land holdings in Evesham, Burlington County, New Jersey were partitioned in 1799 among his five children: Rebeccah, Jacob, Jeremiah, Jonathan, and Hannah. Rebeccah's husband, Caleb Haines, was named. No husband was listed for Hannah, which is consistent with her being too young to be married in 1799 and inconsistent with my Hannah, who was already married to Ezra Adams and with children by 1799.

Jacob's estate papers include a diagram of the land division. Evesham still exists as a township in Burlington County, New Jersey, but it is much smaller today than it was in 1799. These parcels of land were bordered on the east by the Rancocas Creek. I tilted the image of Jacob's land to align north upwards to line up with our modern maps.

I think I found the land! See what you think. The parcels may not be privately occupied. They are east of the Flying W Airport and Resort in Medford.

I'm changing Hannah Haines' name in my tree to Hannah Unknown. Her children's records mostly do not name their parents, but when Hannah is mentioned, she is "Hannah" or "Hannah Adams." I have yet to find a record of marriage for Ezra Adams to anyone in the late 1780s or early 1790s.

Ezra or Edward Sweet (1858-1925)

A surprise child was mentioned in an obituary- or was this a mistake? I think this was a purposeful misnaming.

Lucy Ann Dunn (1822-1910) was a daughter of Nathaniel H Dunn (1790-185x) and Sarah Adams (1796-1882). In 1840 Lucy married George Pearson Sweet (1820-1861). In 1868 Lucy married John Seal (1822-18xx).

I found five children born to Lucy Ann Dunn and George Pearson Sweet: George, Stephen, Emma, Sarah Virginia, and Ezra. The family was living in Trenton for the 1860 census.

Emma died in 1854, so she is not listed in the 1860 census.

Lucy died November 10, 1910 in Bordentown, Burlington County, New Jersey. Her obituary only mentions one child, Edward Sweet, who operated a hotel in Perth Amboy, Middlesex County, New Jersey.

Family tree of Ezra, maybe Edward, Sweet (1858-1925).
His wives were probably related, as they shared the surname Burchell.

I looked for Edward Sweet born to Lucy and George without success. I think the name Edward in the obituary incorrect. Edward was actually Ezra.

But was this a purposeful mistake? Perhaps. In 1910, Ezra Sweet was in legal trouble for "bringing to his place disreputable women" and "carried on a gambling den" at a hotel he kept in Perth Amboy. His "aged mother" was mentioned in a newspaper article.

The Daily Home News
of New Brunswick, Middlesex County, New Jersey
September 9, 1910.
Ezra Sweet was sentenced to two years in prison for illegal activities as a hotel keeper.

Perhaps Ezra was called Edward in his mother's obituary to disguise the connection to the illegal Ezra Sweet, hotel keeper.

Why weren't the other children mentioned in Lucy's obituary? Sarah Virginia Sweet (1849-1931) was still alive. Was Ezra his mother's favorite, no matter his legal indiscretions?

Additional Information of Nathaniel Dunn and Sarah Adams

Nathaniel Dunn (1790-185x) and Sarah Adams (1796-1882) were my fourth great grandparents. This branch lived in Burlington County, New Jersey, including portions that became Mercer County in 1838.

While exploring the lineage of Sarah's parents, Ezra Adams (1768-1824) and Hannah Haines (1771-1824), I uncovered some more facts about the lives of Nathaniel and Sarah.

Revising the Date of Death of Nathaniel Dunn

Previously I thought that Nathaniel's date of death was in the 1840s. Why? Because he was in the 1840 census but not the 1850 census. I did not have any record to document his actual death, but this is not unusual in the 1840s in New Jersey.

"Nathan" appeared in the 1840 federal census in Northampton, Burlington County, New Jersey. In the 1850 federal census, his wife, Sarah, was enumerated without a husband in nearby Trenton with the couple's youngest children, Sarah and David. I will note that it is possible that Nathan Dunn is not the same person as Nathaniel Dunn.

Centralized recording of deaths started in 1848 in New Jersey in the form of ledger books. I found no good match in the index for 1848-1850. Compliance was poor, so an absence of someone from these ledger books does not mean that they did not die in the reviewed time period.

A record of his death could have been recorded in a newspaper, surrogate court proceeding, or cemetery- but no good match was found in these sources either. These records could provide names of parents, birthplace, and place of burial, leading to uncovering the family of origin. Nathan's parents remained a mystery.

On September 22, 2023 I visited Mercer Cemetery in Trenton, where Sarah was buried in 1882. No record of Nathaniel. Actually no family was buried with Sarah. No stone marks her burial spot. Two of her daughters are also buried in Mercer Cemetery, just not with their mother. Lucy (1822-1910) was buried with her husbands, George Pearson Sweet (1820-1861) and John Seal (1822-18xx). Sarah (1833-1916) was buried with her husband, James Burroughs Keller (1830-1864).

As mentioned, I was looking at the Adams and Haines families. They owned several parcels of land throughout the decades in Burlington County.

Upon Ezra Adams' death in 1824, Sarah and her siblings inherited lots partitioned from Ezra's larger 248 acres in Nottingham. I think that this land is now in Hamilton, Mercer County. Ezra's name turned up in searches as Sarah sold her land in the 1840s and 1850s.

in Nottingham, Burlington County, New Jersey in 1825.

Thanks to deeds from the 1850s concerning Sarah's portion of her father's lands, we can adjust Nathan's date of death to after 1850.

In 1850, Nathaniel Dunn was alive and residing in South Brunswick, Middlesex County, separate from his wife, Sarah. In this deed from 1850, Nathaniel and Sarah conveyed land in Hamilton to Andrew K Rowan. Andrew seems to have been a person who purchased and sold a lot of land in this time period. This deed referenced a prior transfer of this land to Jonathan Pullen in 1829. Sarah Adams had a sister, Susan Adams (1799-1874). Susan married Jonathan Pullen (1791-1880).

Recorded April 1, 1850.

Yet I don't find Nathaniel in the 1850 census in South Brunswick or anywhere.

Nathaniel Dunn died after the above transfer of land in 1850 but before January of 1852 when Sarah, described as his widow, transferred more land to Andrew K Rowan.

With this new target date, I still do not see a record of death in the ledgers created at the state level. I have not found an obituary or burial that matches Nathaniel.

The Tumultuous Relationship of Nathaniel and Sarah

Nathaniel and Sarah had problems. How do I know? She attempted to divorce him in 1839. The divorce action did not success with the New Jersey State House of Assembly because Sarah's documents did not support her claims. We cannot tell from the newspaper articles why she was claiming her right to divorce.

Legislative House of Assembly
March 4, 1839
Reports. By Mr Cassedy that the application of Caroline Canfield for a divorce
was within the jurisdiction of the chancellor; and that in Sarah's Dunn's case,
no documents had been presented to substantiate the petition.
Published in the Bridgeton Chronicle

Mention of the divorce petition was found in several newspapers as it progressed through the Assembly, though Nathaniel was not named. Proceedings of the Assembly confirmed that Nathaniel was Sarah's husband and that this was indeed the target couple. (Minutes of the Proceedings are mostly digitized online; however, 1838-1839 is not online. The images were provided courtesy of the New Jersey State Library.)

The year after this attempted divorce, in 1841, the sheriff sold Nathaniel Dunn's land in Mansfield, Burlington County to William Leatherbury (1805-1883) to satisfy a judgment in a lawsuit by William Leatherbury against Nathaniel and Sarah. William was a son-in-law of Nathaniel and Sarah. He was married to their daughter, Hannah Dunn (1818-1889). What the underlying legal action was, I do not know yet. William's mother was Mary Dunn. I do not know if Mary Dunn was related to Nathaniel Dunn.

Hannah was discovered thanks to a DNA match.

William Leatherbury township of Mansfield, Burlington County, New Jersey. Decree of Court of Chancery dated November 1, 1840: William Leatherbury was complainant and Nathaniel Dunn and Sarah Dunn, his wife, were defendants. House and lot of land in the township of Mansfield, town of Fieldsburgh, County of Burlington, and known as Lot number 137 in Jonathan Rhea's town plot, containing one quarter of an acre. Nathaniel Dunn purchased of Thomas Stanmire by deed bearing the date of January 16, 1836. Recorded March 6, 1841.

Now it makes sense why Sarah's was enumerated in 1850 without her husband and why they lived apart as mentioned in the deed from 1850.

Sarah Remarried

In 1856 Sarah married William Marseilles (1788-1859). I only discovered this recently when I was looking for her parents, who were mentioned on this ledger entry. (We do not always find names of parents on these earlier records, but the recorder for this place and time recorded names of parents for almost every couple.)

Sarah did not use the surname Marseilles. She was Sarah Dunn in the census from 1860, 1870, and 1880. She was Sarah Dunn on her death certificate, obituary, and burial record. I had no idea that she took another husband after Nathaniel died. She was not mentioned in his obituary and he was not mentioned in hers.

Further Questions and Research

Who and what caused Sarah and Nathaniel's legal troubles? Did William Leatherbury sue Sarah and Nathan to protect their land and money from forfeiture? Or did William have legitimate legal issues with Nathaniel?

At the New Jersey State Archives I plan to check the Chancery Court dockets for these lawsuits and maybe a divorce.

The Surviving DNA of Jonas Long (1790-1837)

We can turn to DNA to try to uncover the parents of Jonas Long, my 5th great grandfather. We are looking for the identities of 6th great grandparents who lived in the 1700s. We will be working with very tiny amounts of shared DNA.

Spoiler alert: I have not identified the parents of Jonas Long as of this writing.

Jonas resided in Middlesex County, New Jersey and Richmond County, New York, so this is our target geographic area for matches.

Three generations of Long and Merrell

The approach is to identify the descendants of Jonas Long and Elizabeth Merrell (1800-186x) who have tested their DNA. For purposes of this article, we will use the testers at the website Ancestry. Ancestry has a "Shared Matches" feature. The idea is that the matches in common will hail from either the Long side or the Merrell side. The family trees of the possible Long matches will be analyzed for overlap, pointing to ancestors of Jonas Long.

My line descends from Susan Long (1818-1882) from her marriage to Eliakim Marsh (1816-1881). Susan and Eliakim have many descendants among my DNA matches. We can use these cousins to find Long matches, but we must extract the overlapping Marsh and Willis cousins who match through the ancestors of Eliakim Marsh and not Jonas Long.

My closest Long/Merrell cousins also share Marsh/Willis ancestry

Connection to Nearby New Jersey Long

Of note is a descendant of Israel B Long (1794-1886) and Mary Polly Brown (1804-18xx). They lived in New Providence, Essex County (now Union County), New Jersey.

From a book by John Littell published in 1852, we are provided Israel's parents as John Long (1758-1820) and Susannah Valentine (1761-1812).

John Littell, Family Records, or, Genealogies of the First Settlers of Passaic Valley (and Vicinity,) Above Chatham, with Their Ancestors and Descendants as Far as Can Now Be Ascertained (Feltville, N.J.: Stationers' Hall Press, 1852), page 262, accessed July 9, 2026, Google Books.
Feltville is now in Berkeley Heights, Union County, New Jersey.

Jonas Long was probably born in the early 1790s. More research is needed into Israel and his parents to see if Israel and Jonas could have been brothers.

Connections to a Cluster of Long in Pennsylvania

Israel Long's descendant and many of the descendants of Jonas Long and Elizabeth Merrell have matches with a cluster of individuals who trace back to John George Long (1764-1850) and Catherine Barbara Conrad (1771-1832). John George was from The Rhine area of what is now Germany. He and Catherine made their home and family in Northumberland County, Pennsylvania.

Find A Grave memorial page for John George Long (1770-1850)
Buried at Zion Lutheran Reformed Church Cemetery
in Augustaville, Northumberland County, Pennsylvania.

The descendants of John George Long and Catherine Conrad intermarried often. The surnames Haupt and Henninger are often encountered. This may be why they are strongly represented in the Shared Matches.

John George Long of The Rhineland is probably in the generation of the parents of Israel B Long and my Jonas Long. If the Longs originated from The Rhineland, the records connecting Jonas, Israel, and the Pennsylvania Longs will be in Germany, but a more precise location is needed. The name was probably spelled Lang or a variant.

 

Letters Waiting for Jonas Long

During the life of Jonas Long in the early 1800s, mail was not delivered to individual houses; rather, letters and such were sent a local establishment designated as a post office. Recipients were published in the local paper to notify them that mail awaited them.

I found a few such notices for Jonas Long. There may be more, but poor copy of these newspapers, combined with the automated indexing, has not linked them.

The earliest notice appeared in 1818 in The Washington Whig, a newspaper for Bridgeton, Cumberland County, New Jersey. (The town appears as "Bridgetown," not "Bridgeton," in the article. The W was often used in this time period for this town.) This is curious because Jonas Long lived in Middlesex County, New Jersey and Richmond County, New York. These locations are over 100 miles northeast of Bridgeton. It is possible that this letter was meant for a different Jonas Long in that region.

A notice of a letter for Jonas Long appeared in 1823 in the Fredonian in New Brunswick, Middlesex County, New Jersey. This is more consistent with where Jonas was living.

A notice appeared in 1838 in The Evening Post of New York City. This is curious for two reasons. First, this was after his death in 1835 or 1837. Second, a middle initial P was used. This is the only time I found a middle initial for Jonas Long. The location is appropriate for my Jonas Long. Maybe the sender did not realize that Jonas had died. Or maybe Jonas had not died yet- I have found no contemporaneous records documenting a death in 1835 or 1837.

To find old newspapers, I use Newspapers and GenealogyBank. These are pay sites. You can also find newspapers by visiting the website of the local town library to see if they digitized historical newspapers for that town. For example, newspapers for Newark, New Jersey are available for the years 1872-1972 via the library's website with no paywall. Also try searching for the county instead of the town. For example, newspapers from 1814-1950 in Sussex County, New Jersey are available without a paywall.

The Alternate Names of Lucretia Frances Long (1831-1905)

Letitia, or Lucretia Frances, daughter of Jonas Long and Elizabeth Merrell, was a bit challenging to track. She was born about 1831, probably in Richmond County (Staten Island), New York.

"Letitia F Birch wife of Edward Birch" was listed in the probate papers of Richard J Merrill (Merrell), her maternal grandfather, in Middlesex County, New Jersey. She and her siblings signed a release dated October 4, 1865. They inherited their deceased mother's share.

Release signed by six of the children of Elizabeth Long.
Letitia F Birch, wife of Edward Birch, is the focus of this article.

Letitia was also named in her father's probate records from 1860, reflecting his death in 1837 (or thereabouts).

Were these people actually Edward C Birch and Letitia Long? Additional records would help, except there were none easily discoverable.

Where was Letitia/Lucretia in the 1850 census? I do not know. She was not with her mother in Northfield, Richmond County, New York. Presumably she was unmarried.

I did not find Edward Burch or Birch with a wife named Lucretia or Letitia in the census from 1860 forward.

The 1890 federal census was destroyed; however, the Veterans Census survived. In New Brunswick, Middlesex County, New Jersey was Edward C Birch. He served as a private in Company I of the 11th New Jersey Infantry from August 6, 1862 through April 5, 1863.

Yet there is no entry in the New Jersey Death Index for Edward Birch in 1896 or 1897. There are no census entries for this couple.

Using this alternate surname, I found the couple in New Brunswick in the census for 1860 and 1880. In 1860, they had a six month old baby named George DeHart. Also with them was a 49 year old woman named Elizabeth DeHart. (Relations of household members were not asked until 1880.)

In 1880, the original son George was replaced by George born about 1868. Maybe he had a different name at birth because the original George died in 1876. More children were born to Edward and Lucretia: Delphina, George, Joseph. Also living in this household was George DeHart, age 33; and Lizzie DeHart, age 22.

Why two different surnames? I think that Edward's mother, Elizabeth, may have first been married to Mr Burch/Birch, then to William DeHart. Edward may have been born Burch/Birch and used this surname for legal purposes on his marriage record and his Civil War military records. For other interactions, he used his step-father's surname DeHart.

In 1850 in Piscataway, Edward and Elizabeth DeHart lived with William DeHart. There was a ten year gap between Edward and the next child, George. Such an age gap between siblings could indicate a remarriage. This George DeHart is probably the boarder who was living with Edward Birch in the 1880 census in New Brunswick.
