My father, James Mahar, was the son of Joseph Mahar (original spelling Maher..which was Meagher when he arrived in the U.S. as a stowaway and somehow was changed. My brother Tim Mahar, has extensive info on the family, but I believe my grandfather's family was from Thurles, Tipperary. His brother, Patrick Maher, was executed by the British during the Irish Revolution due to mistaken identity in the rescue of Sean Hogan. In my travels, I also found the gravesite of a James Maher, buried in Sackets Harbor, NY in the Military Cemetery from the War of 1812 (very interesting!). Perhaps we're related as well!
