My great great grandmother, Catherine Sullivan Flynn, was born in Ireland around 1830. She immigrated along with at least one brother, Daniel, around 1850 or so. She probably came with more family than that, but I'm not sure. She married Phillip Flynn in Brooklyn around 1858 and they had about 7 children. During the Civil War, they lived in Philadelphia but relocated to Brooklyn after the war. Her brother, Daniel, remained in Brooklyn and served in the Civil War. I would like to know where in Ireland they came from and where she and Phillip are buried in Brooklyn.
