I think we are a generation out. I don't have my grandmother's birthdate memorized but know she died in the late 70's in her late 70's. That puts her birthday in the 1890's.
But the repeating names (Mary, Anna/ie, John) and my family's habit of naming after uncles and aunts (haven't had a new name for generations!) suggests a match of some sort. I'll really have to go through some notes my mother left on this.
