I found additional info on Philip Fishburn who may be the same one you're looking for.Born 1730 in Worrstadt, Germany, arrived in America on the ship Phoenix in 1742. Died 1796 in Baltimore.Naturalized in 1772.Owned property in town of York in York County, married to Barbara (d. 1771) about 1755.Their children are Philip, Jacob, John, Mary Magdalene and Barbara after 1758. Married c.1773 to Elizabeth Klein (or Little) and had children David, Mary, Catherine m. Thomas Mumma in 1797, and Susanna.Was in Frederick Cty, MD land records after 1767, and census of 1790. I am descended through Philip and Barbara and their son John. An extensive study of the Fishburns written in 1992 by John E. Fishburn of Oregon.Hope this helps.
