According to John Jacob's marriage announcement, he married Ann Eliza Wetmore on January 8, 1851 in Candor. Her family was counted on the census in 1850 as follows:
Ann Eliza Wetmore was born abt. 1828. Her parents (presumably), were Abel and Celina Wetmore. Ann had brothers name John, George, and Oliver, and sisters named Lois, Olive, and Phebe. Olive was born about 1843. In 1855, Olive was living with John & Mary Jacobs listed as "sister", age 10.
In 1855, there was a child named Polly L. Wetmore, age 17, living in Berkshire, Tioga County, New York, with Abel and Cerenza Wetmore. Abel was reportedly born in Massachusetts and his wife was born in Vermont. Polly would have been born about 1838 - a perfect fit for Polly L. Jacobs who was living with John Jacobs from 1860 to 1905. Polly wasn't living in Abel's home in 1860. Did Ann Eliza die and her sister Polly replace her?
