My family has been Chicago-based for several generations. My father was Thomas J Rigney Jr, son of Thomas J Rigney Sr, son of Michael Barry Rigney. Michael was born around 1830 in Ireland and emigrated directly to Chicago, probably around 1850.
In response to another correspondent's request... Two of my father's sisters, Kathryn Rigney Walsh and Elizabeth Rigney Stanley, moved as young women to Akron Ohio in the 1940s or 1950s. Elizabeth had no children but Kathryn had several children, one of whom, Brian Walsh, has done a considerable amount of genealogical research and has been an active contributor to this forum.
