Hi James, Sorry I am so unhelpful about Mehigan name. Someone said they may be from Rossbrin which would fit my Wolfes as they were from Ballycommisk which is near Rossbrin (another castle there I think). However I think Castle Mehigan is on the coast near Golleen, and is now a ruin.However it is not so very far away either. Have you ever investigated the castle idea? Regarding the spelling I do not pay a lot of attention to that as I expect they are all same name just different spelling skills or dialects. Am pretty sure my Mehigans were likely RC which could result in some lack of info I suppose as Wolfes were primarily prots. The info I got about these families...some came from RC records but I have found no more early info...Barb.
