I am researching for my children. I have a Robert Emmett Breen 14JUL1891 to 14JUN1976 m Gertrude Quest. His father was Patrick J. Breen b 1860 m Mary Cannon. In the census records I found that Patricks father was Thomas Breen. Also in the records it indicated that Patrick and his sister Anna were born in Ireland so that leads me to the conclusion that they emigrated to the U.S. sometime between 1862 and 1864 when John the next child was born. There was also a Mary b. 1866, Catharine b. 1868 and Thomas b. MAR1870. This is all I have for now except that Thomas' wife was Mary also, b 1840 in Ireland.
