Liz,
As you look at various records for the Robert Caines, please try to write down dates, etc.
For example, the Robert Caine you mentioned with the will in 1896--I don't find the 1896ish burial so I can't figure out which one he is. Do you know how old he was in 1896?

It is frustrating I know to look at a whole bunch of people but that is the only way we're going to find Robert. We need to make sure that each one IS or ISN'T your Robert.
It is just as important to know who isn't yours--for sure.
Just look at who is listed, dates, places.

Robert 1912 is one of the "builder" Caines. He was md Mary from England and had 12 children. I have a bunch of info about him and his Caine line. He was s/o Robert Caine/Ann Christian

Robert 1915 I think was md Ann Kennedy and was a baker. s/o Mathias Caine/Cath Ann Craine.

Thanks,
Donna
