Bernard keon birth around 1869 heard he went to Manchester England to learn a trade in the mills. Then immigrate d to USA around 1900.
I can see 3 possible Bernard Keon births in the period 1864 – 1868 all in the Belleek area at the western end of Fermanagh. Closest to 1869 was Bernard born 1.11.1868 to Bernard Keon & Mary Maguire. Father was a farmer in what looks like Larafin.
You need to try and get your Bernard’s parents names from a marriage or death certificate, or perhaps naturalisation papers, to be sure of finding the right family.
