Hi--I've been doing some research on the Fay family and my husband's great-grandfather was Edward Francis Fay in Cambridge, MA. I'm curious if this is the same family, I think it's safe to assume it is. I don't know much (yet) about Edward F Fay's parents but I think his father was also an Edward Francis Fay.
Also--have you heard of a John (jack) Fay, married a Margaret Fay, they had a child, Catherine, around 1910?
I'll post more info as I get it--I'm going to go to Camb. city hall to do some research this week.
Thanks.
