My O'Kanes are from around the same area.There is a Patrick in my family from Northern Ireland.Anytime I see the name I do try to respond.It is a very common name. I am having my genealogy done and as soon as I can verify it or not I will follow-up with you. My gg grandmother was Anne and she was from a family of 12 siblings, some used Keane and some used Kane but they were all working on the land of a Protestant family. Their father died and since their mom was blind and widowed, they had to help one another survive. Even if this isn't your Patrick, we might possibly have some connection by relation, ex: cousin, uncle, etc....but it may prove promising. I think Anne may have been born in Ballymoney. She was a servant for a while and then a seamstress. I will check some of my files.
