I believe Miles had a sister Mary who married a Thomas Murphy on Jan. 1, 1828 in Niagara on the Lake, Lincoln, Ontario.
Miles Fenlan/Finlon is listed as a sponsor on Thomas and Mary's daughter's baptism record. Her name was Julia and was born March 3, 1833.
Julia married a George Longman in 1853. They moved to the Henry Ill. area in 1862 and then to Grafton Nebraska in the 1890's.
In one of the census records a Peter Murphy (a son of Thomas and Mary) is listed with Miles.
I think we might have a connection. What do you think?
