Hi Kathy,
We are researching Thomas (1861-1948) and Catherine (Kelly) McCormack from Derreen. Some of their children, including my husband's grandmother Honor came to Boston in the 1920's.
We believe Thomas was the son of Patrick and Mary (Gacquin) and had two brothers Patrick and Michael. Thomas and Patrick both stayed in Derreen and Michael came to Boston.
We'd love to share information. Thanks,
Paul and Kate
