I can help. George Peter Utt was born in St. Louis in 1894 and died in Kansas City in 1947. His first wife was Marion, and their daughter was Mary Jane, b ca 1915. [Sound about right?] He remarried, to Minette B. Stecken.
I have lots on this branch of the Utt family, but we lost track of your mother after the divorce.
