Emigrated to Canada to Lot 8, Conc. 2, Fitzroy Township, Carleton County in 1835. He does seem to show up on the 1851 census (listed as age 73, and a farmer born in Leitrim,Ireland), so his death date of April 1838 is probably wrong. In the 1851 census, his family living with him includes: John, Margaret (wife),Robert (son, age 24),Eliza (daughter,age 26).
His marriage year of 1814 is probably wrong as well, unless he was married previously to someone else.
It is thought that he was born in the Drumreilly Parish in Leitrim. (His son George was, according to his tombstone in Beechwood Cemetery, Ottawa).
Jean M. Story (writing on Sep. 8, 1977) thought that he was born in 1773.
