Do you know any Boundy with those names?

James - 1868
Elwin - 1886
Sarah E - Boundy was her maiden name. Married Edwin Milnes who was born in 1846. I don't know when she was born. I think she died young.

I know that Elwin/Elwyn was married to Gertrude and lived in Modesto, California. James was Elwin's father.

I believe that James was married to Genevive.
