I am seeking connections with Ratigan family from Chicago. Names are Kathryn (b.1915), Joseph (b.1917) and Robert (b.1925). Parents were Peter Ratigan (b. Roscommon 1888), and Elizabeth Gallagher (b. Galway 1889). Elizabeth and some of her siblings left Ireland pre 1900 and never returned. She would have been my grand-aunt. Would love to hear about them.
