G-G-Grandfather Michael came from (unknown place) in Ire.; probably with his son, Martin (et others) abt. 1850-1870. Martin married Alice (?) and they had at least James and John Robert, who had John Robert (who was later adopted by an aunt, changing his name to Robert John Killian). Michael and Martin apparently settled in Mitchell Township near Sheboygan, WI. Can anybody make any connection to these ancestors?
