Looking for information on the Allen family from Philadelphia. My great grandfather's name is William Allen born in Jan 1864 in Philadelphia. His parents names were Reuben Allen born PA and Kathryn (nee Coleman) Allen born GA or VA, but I can find no information in the US Census 1860, 1870, 1880 on these people. The vast quantities of Allens have made the search difficult. It is also possible that they may have used nicknames like James or Rose. My great grandfather William lived most of his life in the Grays Ferry section of Philadelphia. He married Anna Marie Downey in Sept 1885. They had 17 chidren starting in 1886 Reuben, Alice, Anna, Rose, Agnes, George, Joseph, Francis, William, John and Thomas-1913. Any help would be greatly appreciated.
