Hannah, an earlier child of Nathaniel Dunn and Sarah Adams

Another child of Nathaniel Dunn (1790-1840s) and Sarah Adams (1796-1882) was discovered, thanks to Ancestry's DNA matches.

Nathaniel and Sarah were paternal 4th great grandparents. They lived in Nottingham, Burlington County, New Jersey. This area later became part of Mercer County. I descend from their son, Ezra (1821-1898). The date of death and the parents of Nathaniel are not determined yet. Sarah's parents were Ezra Adams (1768-1824) and Hannah Haines (1771-1824).

This map from 1834 shows the New Jersey counties at the time Nathaniel Dunn and Sarah were raising their family. The area of Burlington County where Nathaniel lived now lies in Mercer County. It was near the borders of Hunterdon, Middlesex, and Monmouth Counties, as well as another state, Pennsylvania. Because of changing borders and close proximity to other county and state lines, records for Nathaniel may be spread across many repositories.

Among the DNA matches at Ancestry are other descendants of Ezra Dunn, along with descendants of Ezra's sister, Lucy, and brother, David. 

The "Shared Matches" function produces dozens of other matches. These people do not necessarily share ancestors of Nathaniel or Sarah. If the match were on the same segment of DNA, then we would suspect a connection to Dunn or Adams. Ancestry will not reveal which segments of DNA are shared, so this is a drawback to this feature.

Someone matched in the fourth cousin range and provided a limited family tree. I honed in on the Burlington County, New Jersey branch and a great-grandmother named Hannah Dunn, wife of William Leatherbury (1805-1883). They had children from the late 1830s through the early 1850s.

Hannah died October 23, 1889 in Fieldsboro (Bordentown), Burlington County, New Jersey. I traveled to the New Jersey State Archives in Trenton to view her death certificate. Her parents were listed as Nathaniel Dunn and Sarah Dunn! She is tentatively placed as the oldest child of Nathaniel and Sarah According to her death certificate, she was 70 years old in 1889. This places her birth around 1829. In the 1850 census, her birth year would be attributed as 1819. The earlier record is usually more accurate for age.

Her place of birth is listed as Mercer County, which was actually
Burlington County at the time of Hannah's birth.

I also copied the death certificate of Hannah's husband, William Leatherbury. He died September 20, 1883 in Bordentown, Burlington County. He was born in Maryland to William Leatherbury and Mary Dunn. More documents are needed to determine if this really was his mother's name.

Hannah and her husband William were buried in Bordentown Cemetery. I added them to Find A Grave. One of their children, William (1840-1909), was also buried in this cemetery.
