Hi Listers, I'm new to this list and am asking for help with the following: Need help re Pittsburgh (Allegheny City) City Directories 1880-1900. According to the 1870 Allegheny Co Fed Census, Michael CORBETT along with his wife, Mary GIBBONS CORBETT, their son, John, their daughter, Margaret Josephine, and Michael’s sister, Mary CORBETT, were living in Pittsburgh’s 12 Ward. By 1880 Michael’s sister, Mary CORBETT, was no longer living with the family; but Michael and Mary had added two daughters, Mary and Annie. In the 1880 Census, the family was living on Hillside St in Allegheny City, 12 Ward. In 1888 Margaret Josephine CORBETT married Patrick SARSFIELD somewhere in Allegheny Co and lived the rest of her life in Beaver Co. There is not a Michael CORBETT listed in the 1900 Allegheny Co Census. When did Michael leave Allegheny Co or did he die between 1880 and 1900? Seeking descendants of this family
