I was politely reminded about another posting I made that I also need State, location, etc. I see I did not put that in this posting either so here it is.
Blanche Knupp Davis was born in Wood Co., WV and married in Parkersburg, Wood Co., WV. This is derived from her marriage certificate, 1900 & 1910 Census Records.
Earl Davis was born in Wood Co. WV. This is derived from his marriage certificate, and 1930 Census Record.
I've also found from the 1930 Census that Earl & Blanche had 3 sons. Carl, who I mentioned, was born in West Virginia, Kenneth born 1921 in WV., and William born about 1929-1930 in WV.
I hope this helps.
