I hope this was okay to start a new thread, but I have an ancestry account and wanted to post findings for the Davidson geneology. If this is not the right place for this, please move. Thank you! I found the SSDI for Robert H Davidson. The H is for Holden, which was his mothers maiden name. Birthdate is August 3, 1885- death June 28, 1946. He was buried in Rexburg, Madison, ID In 1900 he lived with his family in Idaho. It shows that his father, John M Davidson was born in Scotland, his mother, Harriet, was born in Utah. There is also a John H Davidson aged 24, William T Davidson aged 22, Robert, and May Davidson aged 11. In 1910 he was married to a Nettie T and living in Wyoming. Robert H Davidson - 24 Nettie T Davidson - 21 Robert L Davidson - 3 Floyd E Davidson - 2 Harriet Davidson - 7/12 Less than a year old? By 1920 they were back in Idaho, as they are in 1930. There are several people living in the house in 1920. Robert H Davidson - 33 Nettie T Davidson- 31 Robert Leon Davidson - 13 Floyd Ellis Davidson - 12 Harriet H Davidson - 10 Elwood S Davidson - 8 Verne S Davidson - 6 By 1930 there is a Roy Davidson aged 7, and a Neva aged 3 in the house. None of the other children are listed in the household. Nettie died in 1931. Robert Holden remarried to a Susannah Pauline Tanner(Susannah was born about 1910) on July 27, 1934 and had two children. I am uncertain, but think that her/their children were: Dell Reed Davidson born Dec 7, 1935 in Idaho, died Dec 16, 1997 Sacramento, CA (Incidently, Dell Reed's social security middle numbers have a 44 in them) Clyde Lee Davidson born Feb 11, 1937 in Idaho and died Jan 23, 1993 in Sacramento I have not found much on Dell, but Clyde was married to a Diane in 1971 in Sacramento. She remarried someone else in 1976 in Butte, CA Elwood was born 1911-died 1856 Robert Leon was born 1906-died 1952 So...the grandson (from the DNA sample) has to be the son of one of these children listed above. There is a WW II draft registration for Robert Holden Davidson. I found a family tree on ancestry, but interestingly enough there is only one child listed- Verne Stevens Davidson, who was born in 1913 and died in 1982. Verne was born in Oregon and died in Idaho. Verne was married to a Camilla June Smith, but there are no children listed. I have been able to find a birth or SSDI for Verne. Camilla was born June 25, 1914. She died in 1997. IF BK is related to this family, I would think either Verne or Roy would be his father, based on age, but who knows. We are only looking at the male relatives, right? I am still searching for info on Roy. He was born about 1923.
