Looking for information about my paternal grandmother's family. What I have found is that Margaret was born Aug, 1898 in Michigan. Date of death was Oct, 1989. I believe her mother/father's names were Mary and Michael. Margaret had two sisters Catherine (b. Sept,1896) and Honora (don't have date of birth). The three sister moved to Chicago, Ill. Margaret married Joseph E. Duffner. Catherine married Samuel Caldrone. Does anyone have any additional information that would help me?
