Family Tree Repair: Hiley VanDerHoof 1803-1888

I was excited to find this family tree with additional details about my fourth great grandmother, Elizabeth Vanderhoof (1799-1878). Then I realized the creator combined Elizabeth with Hiley Vanderhoof (1803-1888). These were two different women living in Morris County, New Jersey in the 1800s.

One of the red flags on this tree is that the person died in 1878,
but was enumerated in the 1880 federal census.

Hiley was spelled differently in various records. "Hiler" is a surname in the area. I do not know if this is the source of Hiley's first name.

• Hyla on her 1823 marriage record to William Cook
• Hiley in census entries
• Hylia on her death certificate
• Hila on her gravestone

Hiley and Elizabeth were two different people. They were probably sisters. They married two Cook brothers.

Hiley's first appearance in the census is in 1850 in Rockaway, Morris County. Her husband, William Cook, is not listed with her and is presumably deceased. In her household is Jacob Cook, age 26, married within the year. Sarah Cook, age 20, married within the year. William Cook, age 11. Sarah was probably Jacob's wife and not a daughter of Hiley and William. She is not with Jacob in the 1860 census and presumably died between 1850 and 1860.

William Cook married Sarah J Anderson (1845-1928) in 1862.

Elizabeth died in 1878. She was buried with her husband, Stephen Cook, in the small Cook Cemetery in Denville. The few remaining stones are nestled on the grounds of the Rockaway River Country Club Golf Course.

Hiley was buried at the Rockaway Valley United Methodist Church Cemetery in Boonton. The year is incorrect on the stone. She died in 1888, not 1886. The death certificate is below.
