What does Flynn mean?
Ó Floinn means “descendant of Flann.” Woulfe explains Flann as a personal name connected with the color red or a ruddy appearance. English-language forms recorded by Woulfe include O’Flynn, Flynn and Flinn.
Is Flynn one Irish family?
Flynn belongs to several separate families. Woulfe records Ó Floinn lines in Roscommon, Mayo and Cork, each with its own territory, and found all of them still well represented in their native districts.
Where were historic Ó Floinn families found?
- Roscommon: Woulfe records an Ó Floinn family of Síol Maolruain in west County Roscommon, around Kiltullagh and Kilkeevin, and another ecclesiastical association near Boyle.
- Tirawley / Mayo: another Ó Floinn family was associated with Magh hEleog in the Crossmolina area, with an erenagh branch connected to Errew on Lough Conn.
- South Cork: Woulfe records an Ó Floinn family of Ardagh, associated with territory in what became the barony of Ibane and a seat near Skibbereen and Baltimore.
- Muskerry, Cork: another Ó Floinn family held a district known as Muscraidhe Ui Fhloinn, later anglicized Muskerrylinn, between Blarney and Ballyvourney until the MacCarthys of Blarney displaced them around the start of the fourteenth century.
Woulfe also notes an Ó Floinn tradition connected with Uí Tuirtre under the related form Ó Loinn. In Antrim the aspirated F fell silent, which is why O’Lynn and Lynn appear there. A family’s county and parish point to its branch.

How to research a Flynn or O’Flynn ancestor

County and parish are especially important, since they show which regional Ó Floinn family a line belongs to.
