My great-grandmother, Catherine Conlan, had a brother named Andrew. Andrew Conlan, son of Luke Conlan and Mary Carroll, was born 8 Feb. 1825. Do not know what happened after that, although Luke and sister Jane moved to New York. They were born in Togher, Parish of Clonmore, County Louth, Ireland.
Luke married a Mary and had 7 children. Jane married Edward Quinn. Have lost touch with the New York cousins.
