Apart from a few families named from English place-names or, in the case of Paton and Patton, alternatively from a diminutive of the personal name Patrick, these surnames are derived from the Irish Ó Peatáin. This in its place of origin - near Ballybofey in Co. Donegal was first anglicized as O'Pettane and later became Patton. Murtough Ó Peatáin whose death in 1178 is recorded by the Four Masters, was of the Cenél Moen. In Connacht the anglicized form is usually Peyton, mainly found in Co. Mayo. This branch of the sept seems to have followed the O'Donnells from Donegal in the early seventeenth century. The prominent landed family of Laheen, Co. Leitrim descend from an English clergyman, Rev. Thomas Peyton, Dean of Tuam in 1625. Prominent in Ireland were Christopher Peyton, who carried out the Desmond Survey which bears his name in 1586 and Sir John Peyton, surveyor general (ordnance) 1684.
