Can anyone help me locate information on my mother's father Michael KOHLER, possibly known as Frank. The only information I have is from a certified copy of my mother's birth certificate from Cook County, Ill. However, she gave the information herself and had it witnessed. My mother's birth certificate says her father was 27 years old when she was born and a streetcar conductor. Orphanage records at St. Mary's in DesPlaines, IL show my grandfather's name as Michael Kohler and his wife as Catherine mcDermott Kohler. My mother's name was Genevieve Kohler. Mother believed he abandoned his family and went to California. Michael(Frank) KOHLER'S wife Catherine seemed unstable from orphanage records. I really don't know how to proceed.
