You do have my family tree . I can Not find Alvin Doty middle initial or middle name anywhere online..
I found Alvin is buried in Forest lawn Cemetery in Saginaw, Mich. & His is buried in lot #446
It's a unmarked grave- No marker's of any kind .
Unless my info is wrong - I found Alvin was born 1896 -1962..
I discovered Lucius & Hannah Doty is my g.g.g grandparent's I'd love to compare notes with you at - firstname.lastname@example.org
