Idr, I haven't checked this site in a while and just saw your message.I was excited to see your info about Edward's sponsors.Edwards father was James b.2/5/1815 who married Ann McMahon! My John b.1848 did indeed have an uncle John b.4/15/1821 who married Mary Larkin. Hugh b.1818 could have been a first cousin to James and John. You said Edward was from Teer.My research has his parents living,at least at one time in the townland of Mounthill.I am going back over to Ireland in July and hope to get some further info.The McConville gathering is there in July so what better time to go?
Best of luck and hope some of this blends with your info, Jerry McC
