Edmond Jacob Springer was my great grandfather and would have been a half first cousin*** to Mary Springer, wife of Rue B. Stone, mentioned in the article you posted.So, that would make Mary Springer, a sister-in-law to Maude Stone.
I'm unsure who M.F. Springer is, unless that is Mike Springer.Mike Springer was a brother to Edmond Jacob Springer.The Clarence Springer mentioned, is the older half-brother of Mike and Edmond.
*** same grandfather; Benjamin O. Springer, but different grandmother.Edmond J. Springer's grandmother was Benjamin O. Springer's first wife, Eliza Batchelor and his second wife, Mary McMechan, was Mary Springer's (Rue B. Stone's wife) grandmother
Thanks again for posting these articles, it is so wonderful to see them and connect the family.
I am putting together a book for my Great Aunt, who turned 90 this month.She is the only surviving member of Edmond Jacob Springer's immediate family that knew him when he was alive.Edmond J. Springer died in 1921, so there is much to be learned about his family.
