Sorry I don't have any information for the names you are listing. I do re-call my Dad mentioning the name Bernadon, and I have a cousin Angela Ret in Queens NY. But not the same age as you're looking for. You will find that there are many named Ret, D'agnelo, Bernadon, Toffolo that married in the early 1900's, so it's hard to pin down direct relatives, although ultimately therte's some relationship.

Good Luck - Gene Ret
