I can't edit my original post, but I do have some more info now. Alex & Edith Bain lived in Taylor, MI. Alex died in 1997, and I believe Edith died on Dec 15, 1965. This is based on records from Glen Eden Memorial Park in Livonia, where their son Bruce is also buried. Bruce was KIA in Vietnam in 1970. Cemetery records show a burial for Sarah E. Bain. I've only known her name as Edith, but her mother was also Sarah (though she went by Sally) so her name could easily be Sarah Edith Booth Bain.
I'm looking for Edith's obituary now.
