Not only am I interested but I also administer the "Airghialla Mag Uidhir" FTDNA Project. We are a group of surnames that relate back to "Uidhir" (annals noted 956AD) and Donn Carrach Maguire (d-1302). Mag Uidhir is old Irish for Maguire/McGuire. Through extensive Y DNA testing we have found an association between the likely descendents of both Uidhir and Donn Carrach (as well as other progenitors in the tree). The various sept surnames include: Maguire/McGuire, McAuley, McMahon, McManus, Corrigan, Gurry/Curry, Byrnes/Breen, McOsker, McCown/McKown, McDonald, McCadden, Donohoe and more.
I've only recently joined Wikitree, so my own GEDCOM is awaiting approval. However, this special project sounds promising indeed!
