Hi Otto.
Mm, interesting. I dont have marriage cert for Henry, but the Henry you found could be valuable, and, the names you have with him on the fragment. Then, it could be a blind alley. I am cherry picking with this rellie. My hope was to possibly find a birth record of one of the kids mentioned, born in Armagh to (Henry b1812 Armagh) as Great grandfather Charles, (Henry's son) is a definite birthdate 1845. I thought this would give a better address/ location but realise this is iffy. Which church

If the Henry you found is Henry snr, he would have been 50 when Henry Jr was born. Blimey, I am carried away, you must be fumbling through this................ I really appreciate your time with this. Oooooo, it's difficult to track people in Ireland.
Thanks so much, Dido.
