My uncle was Lawrenc K Sweeney (1918-2003) his parents were Edward A (1884-1955) and Florence Witzel Sweeney. Edward A's parents were Edward A? (1857-1904) and Jane Elizabeth Malone Sweeney (1860-1929). I blieve his parents were Edward McSweeney (b.1824) and Ellen (d 1880).
I would love to exchange information with anyone who has informaiton on this family.
