The Black S of Couty Tyrone

I'm looking for the family or those related to a John Black born 1831 or 1832 who came to the US from somewhere in county Tyrone. He was a blacksmith had 5 or 6 bothers and was a proestant. He originally landed in New Brunswick, Canada then settled near Ft. Covengton, NY. Thank you for any help you can give me.
