My GG Grandfather was John L. Gallagher, born in Michigan ca. 1851. He came to Cleveland sometime between 1870 and 1880. I believe he is the son of John Gallagher and Sarah McCarty.
John L. (1851-1916) married Margaret Lynch (1855-1898) and they had 4 children. John Vincent, Mary L., Joseph Patrick, and Sarah. My G Grandfather was Joseph Patrick Gallagher (1880-1908) who was killed in a fall from a smokestack he was cleaning a month before my Grandmother Mildred was born. He was married to Sarah Lally (1884-1951)
