I've been battling my Davis surname quandary for at least thirty-five years, ever since I started doing genealogy. Davis?, What quandary? I could never find the paternal line for Joseph Davis, born 1840/41 in Pennsylvania. I finally met a cousin and fellow researcher, Ethel Daley, who had an old, Kennedy family bible that gave Joseph's name as Leeman--bible spelling--when he married Sarah Ann Kennedy in 1869 in Allegheny County, Pennsylvania.
See my blog of about the Davis quandary.
Frank Davis, a direct, lineal, male descendant of Joseph's, had his DNA done and low and behold, it provided a 37 out of 37 marker match to the family name of Hamilton. I immediately emailed Mr. Hamilton and learned that his birth name was indeed Boyd and that he had been adopted at the age of 2 by a Hamilton family. So, Joseph's father was a Boyd. Unfortunately, women are only counted in the 1840 census and not named, so I'm not aware of the families living close to her or, indeed, where she was living in 1840. My suspicions are she was living in Middlesex Twp., Butler County, Pa. since that is where she shows up in the 1850 census living in the Samuel Davis household. They married that year. But that doesn't give me Joseph's father. I need to find her living either with or near a Boyd family in 1839/40 and I suspect it was in Middlesex Twp., Butler County, Pennsylvania. The search is on. Join me, I need the help.
