Jim:
Found some info on Edwin Burdick on Ancestry. Edwin died in 1976 and his wife died in 1991. They had a daughter named Gail who died in Tuscon, Pima Arizona in 1998. Not sure what the chances are of getting info on Bentley from people mentioned in her will. You can add it to the list for future reference.
Do you know how Margaret Fuhrman met John Pic or anything about her Hungarian background? They had a son born in 1966, he may be able to shed some light on their relationship.
Do you know when Edwin Ekdahl divorced Marguerite Oswald?
NYPL is still processing my order.
