I'd love to help Ray, but I live in Brooklyn. Israel Heyes'
granddaughter, Mary Robinson (nee Hornby)immigrated to Massachusetts with her daughter (my grandmother) Frances in 1914.
I do subscribe to ancestry, and I have spent an awful lot of time reading on-line parish registers, but I suspect you do the same.
I do have a question to which someone there might have an answer. Although my grandmother Frances Hornby was Catholic as was her mother Mary, Israel Heyes' name suggests he was probably some form of non-conforming Protestant. Anyone know?
Also, if Ray or anyone else is interested, I have more information about the Israel Heyes family. I don't, however, know any other living descendants--that is, other than my own American cousins.
