Thank you so much for responding. I have the information for Robert's mom and dad, his mom was actually Daisy Hilda Wormald. I don't know if it was a misspelling of her last name or Robert didn't know her real last name.I'm trying to find Robert's wife and children so we can find out who raised him, where he grew up, etc. My grandfather Benjamin H. McMahon and Daisy Wormald married in 1925 in Canada.He was married to my grandma (Anna Lee McMahon) from 1914 until 1925. So when Robert's birth was recently discovered, it was a surprise to most of us ... my grandfather's family and Daisy's family.
Because Robert's death is listed on the Social Security Index, he must have had children who received death benefits from SSA.The 1940 Census may be a help to me, but it's quite tedious to go through page after page, since not all states have been tabulated for the census. There was an article in a paper about Robert's death because he was the Asst. Superintendent of the Game Farm in Walla Walla. He fell off a tractor and suffocated in the dirt. Thank you again I appreciate your help and I will look at the Walla Walla site to see if I can find his obituary ... the Death Certificate does say he was divorced.
