L21>DF13>L513>S5668>Z16430>FGC9798>FGC9811: Associated with McGuire

Dennis Fitzpatrick, who traces himself to County Meath has several STR matches to the surname McGuire. A possible historic link with neighboring County Fermanagh is detailed in 'The Fermanagh Story', which states "the Fermanagh Fitzpatricks were a branch of the Maguires".

Specifically, Thomas Mor I (The Black Gillie - Dark Attendant or Guard) (1395-1430) was a descendant of Donn Carrach Maguire (1264-1302), the first Chief Maguire, King of Fermanagh. Septs under the protection of Thomas included Gilla Pádraig of Fermanagh of the Maguires.

Alex Williamson's Big Tree (ytree.net) indicates a cluster of McGuires who are L513>S5668>Z16340>FGC9798>FGC9811>FGC9822>FGC9809. Hence, Dennis is associated with these particular McGuires and more advanced SNP tests will determine if he also shares the SNPs downstream of FGC9811.
