From Patrick MacAuley (except for the first sentence)
You must admit that the title is an attention grabber. "It means Owen MacAwley the Black. His sons could have used a McOwen surname. His death is mentioned in the Annals of Ulster for 1505. Unfortunately, he is not included in the Geinealach Fermanach, and not much more is known about him. He was probably the son of Brian MacAwley Maguire (d. 1466)or Philip Reagh MacAwley (d. 1480). It's remotely possible that this man's descendants would have used the name McOwen as a "local
patronymic" which could have eventually become a legal surname."
I had written to "Walter McCauley" because we have a spectacularly high percentage of a probability of a Most Recent Common Ancestor (MRCA) within the last 12 generations. Again quoting Pat MacAuley "Father Walter is a retired Jesuit priest, who is living in a seminary and is a fourth cousin of my father, and can trace his ancestry to Glangevlin in County Cavan circa 1800. (About one mile from Maguire's Chair.)."
"Father Walt is a 36/37 match with the Donn Carrach Maguire profile. His only mutation is one that the three of us share--at CDY-b we have 38 instead of 37. I'm still not sure whether this means you are from the ClanAwley line, or whether you are from another Maguire line which independently acquired the mutation. Since Daniel Warrington McCauley has the "correct DCM" 37 at CDYb, the mutation was probably acquired after the McAuley sept had formed."
"I read with great interest your latest discovery in southern Tyrone. There are a lot of Maguires in southern Tyrone and my Uncle Paddy's mother was a Maguire from Tyrone. Parts of present day Tyrone, especially Kilskerry Parish, were probably part
of Maguire Fermanagh until about the 1560's when they were seized by O'Neills. Although the Tyrone lead should be examined, my feeling is that Edmond McGuire McOwen
of Tyrone will probably not be the man we are looking for."
My thanks to Patrick MacAuley for his guidance and encouragement during my McCown line research. Every body needs friends, and I am very grateful to Pat, a good friend indeed. Good friends such as Pat, Barry McCain, the fair Coane and many others are a benefit I didn't expect from genealogy. Also, the efforts of William Roulston and the Ulster Historical Foundation are greatly adding both their research talents and discipline to the process. See their website at www.ancestryireland.org.
