A Cluster of Maguire DNA Families

One McGuire in particular has a great many DNA matches that show promise of shedding light not only on his family but perhaps illuminating new information on the rest of us with Maguire DNA. He has the highest matches
with the reconstructed DNA of Donn Carrach Maguire, first Maguire prince of Fermangh of any of the Maguires tested to date. This reconstruction of the DNA of Donn Carrach Maguiire was the result of a DNA study by
Trinity College, Dublin using hundreds of American test subjects from all of the major families of Clan Maguire.

My personal results to date indicate a genetic distance of 4 with Donn Carrach at 37 markers. Since he died in 1301, a little more than 800 years ago, there has been ample time for accidental mutations to occur in the DNA of his descendants. Brad McGuire's line has the fewest mutations in that time, in fact, appears to have no mutations. Since all of the principal families of the Maguire Clan are related to the ruling line by blood, this Clan is the basis for an excellent DNA study and supporting documentation.. Again in the case of my McCown line, we now have high quality matches with all of the major families of the Clan Maguire. They are Maguire, McManus, MacAuley and McMahon.
