Last name: Regan

This is an anglicized form of the Olde Gaelic name O' Riagain or O' Raogain. There were three main septs of this family in Ireland, each with separate origins. The first belonged to Counties Meath and Dublin and were one of the Four Tribes of Tara (Tara was the seat of the high kings of Ireland). The second sept descended from Riagan, nephew of Brian Boru, High King of Ireland, (1002 - 1014). They ruled in the ancient territory of Tuathmhumhan (Counties Clare, Limerick and Tipperary). The third sept resided in Carbery (South West Cork) and were kinsmen of the MacCarthy's. Fineen MacCarthy, writing in 1595, mention fifteen families living there. The Reagans emigrated to the U.S.A. before the Famine a distinguished descendant being Ronald Reagan. The first recorded spelling of the family name is shown to be that of Maurice O' Regan (Gaelic O' Riagain), which was dated Born circa 1125 wrote an account of the Norman Inavasion, during the reign of "High Kings of Ireland with Opposition", 1170. Surnames became necessary when governments introduced personal taxation. In England this was known as Poll Tax. Throughout the centuries, surnames in every country have continued to "develop" often leading to astonishing variants of the original spelling.

My grandmother was Mattie Regan as a maiden, marrying my grandfather David McKay in the later part of the 1800's. Mattie, we were told, was half Cherokee. I would like to know if this is true.She once wrote to the BIA asking for a roll number but was declined because she was a Western Cherokee.

Randy Regan

Hey guys! Besides my siblings and dad, I am the only African American I know with the last name Regan. My dad wasn't close with his father so he can't tell me a lot about the origin of our name. I've been having some difficulty with the research. I was wondering if any of you guys had an idea where to start?
