These are one set of my maternal great great grandparents. I checked the National Archives in Phily on Aug 20. Both James and Bridget show up on 1860 and 1870 Federal Census for Philly. Did not get time to check 1880 census yet. I have found James and son Robert grave sites. Bridget is not buried with them. Have not found her death certificate yet in Philly City Archives. Contact me if you want to discus further.
