John Davern was an "Irishman", however, records show that he was born about 1739/40 in Fairfield, CT, so he was probably of Irish descent. He served in the French and Indian War in 1761 as a Corporal and later as a Sargeant. See record. Lois Knapp was from a long established Fairfield, Connecticut family.
Children of John and Lois were David, John, Talcott, Lucy-Jane, and Betsy.
Talcott had five children that we know about: William, Milo, Abigale, Erastus, and Laura. However, the census data shows the possibility of four more children (2 daughters, 2 sons) whose identies are still unknown. The identity of Talcott's wife was a mystery for over two years, but we now believe her name was "Temperance" as shown in a deed when Talcott sold some property in 1815.
The 1800 census shows that Talcott lived in Augusta, Oneida County NY. The 1810 census shows that he lived in Smithfield, Madison County NY. The 1820 census shows that he still lived in Smithfield, Madison County NY. Two deeds recorded for property purchased and one deed recorded for property sold show that Talcott and Temperance lived in Madison County between 1807 and 1815.
The 1830 census shows that an "older male" lived with Erastus and his wife Polly in Rock Creek, Morgan township, Ashtabula County, Ohio. This older male was probably Talcott; he would have been about 62 years old in 1830.
Early 1900 newspaper articles indicate that Talcott moved to Morgan township in the 1800's, probably between 1820 and 1830, and built a log cabin on the banks of the Grand River. Later, Erastus built a very large house near the site. This house was home to many descendants of Old Talcott as well as a hide-out for run-away slaves.
Talcott, William, and William's son Nehemiah and daughter Temperance, joined the Shaker community at North Union (later Shaker Heights).
