I will be on the look out for Lyman Davids or any Lyman naming pattern that may tie in with the generations.Right now I'm hoping I have found a connection to another of William and Lydia Davids daughters.I suspect that Zada belongs as one of the children of William and Lydia.Joel Munger and his wife Anna Davids moved from Cayuga County, New York to Branch County, Michigan and in the 1860 census there was a male child by the name of Addison Turner living with them and he continued to live with Joel in Allen Twp, Hillsdale, Michigan.I never could figure who he belonged to.In doing research on Zada who records show was born in Rensselaer County, New York (where William and Lydia were married and who by 1810 census show four under ten years of age females in their family)she married Gideon Tripp in Renss Co and by 1850 census they are in Lapeer, Lapeer, Michigan and there is a Phebe Turner living with them who is their daughter. Phebe was born 20 Dec 1822 New York.
Phebe married Simeon Turner (who was b abt 1818 New York), in 1839 and had a dau Rebecca b abt1857 maybe in Lapeer, MI and another dau b abt 1859 and a son (no names on last two) abt ?1861. Doesn't seem to be much info on this family in the Ancestral File.
If Zada is a sister to Anna Munger, as I believe, then this male child with no name could be the Addison who is 4 yrs old in 1860 and would be a nephew of Joel Munger's first wife Anna Davids.
If you can shed some light on this I would like to hear from you.
One more thing I found that Lydia Finney had a sister six years older than her who lived with her husband and children at Sand Lake, Rensselaer, New York.This may explain why Lydia and William Davids married at Greenbush, Renss., New York in 1799 when Lydia's parents lived at Monkton,Addison, Vermont.The sister was Rachel Finney who married Lemuel Hunt.
I've always felt that William and your John are related. Joyce
