I am looking for information on family of Mary McAllister (1790-1861). She came from Ireland (don't know where) on May 31, 1848 into Philadelphia as a widow with Patrick (19) and Thomas (not listed), Thomas' wife Biddy and children Isabella (3) and Patick (2). 1850 census shows them living in Berks Co., PA. 1860 census shows them living in Venton, Ohio. 1870 census shows them living in Venton Co.,PA. 1880 census shows Patrick and family living in Stewart Co., TN. Thomas's children: Isabella, Patrick, Mary Anne, Sara, Thomas, John, Peter, Joseph, Katty. Patrick's children: Thomas Francis, Mary Anne, Joseph, Bridget, Patrick, Katie, Peter, Sara. Thomas Francis moved with wife Mary Alice Diggins to Pioneer, Louisiana. Do you have any connections. I know the repeat of given names make this quite difficult.
