My great, great grandfather, Maurice A'Hearn (I have also seen the name spelled Ahern and Ahearn) married Johanna Connell, I believe sometime in the 1840s.They lived in Athea, County Limmerick.They had at least 3 sons, all of whom emigrated to the United States and settled in Cortland, New York.The sons:John A'Hearn (b. 1863, d. 1929, married Mary ___ - est 1880s);Maurice A'Hearn (b 1874, d 1926, married Catherine "Kitty" Kane in 1899; children John, Josephine, and Elizabeth) and Jeremiah A'Hearn (b. 1868, d 1929, married Maria Kane in 1888; children - Thomas, Morris, Charles, Henry/"Harry", and Joseph Francis.
Jeremiah A'Hearn was my great grandfather.Joseph Francis A'Hearn was my grandfather.I grew up in Syracuse, New York.
If you have any information on this branch of the family (or could steer me to any helpful sources), I would be most appreciative.
