|Grahame||Very numerous: Ulster mainly, also Leinster. Scottish, 17 cent. They were an Anglo-Norman family who settled in Scotland in 12 cent. However, in Connacht it is likely to be an anglicisation of Ó Gréacháin, which occurs as Grehan and Greham. SI & SGG.|
|MacGraham||Very rare: Dundrum (Down). Perhaps a Scots Gaelic version of the Norman Graham who settled in Scotland in 12 cent.|
