In a search for William Perkins Mains on Ancestry.com I have not been able to locate any deaths in 1960 in the state of Montana for William. I have been able to find the marriage record for William and Virginia so one piece of information has been corroborated. I have yet to find a marriage for William and Helen.
I believe the next step will be to search for Helen. Anyone who finds any information please let me know.
Today, the 13th, I called Bellefontaine Cemetery, where Mary Virginia is buried and they confirmed that he is not buried there.
