Ó Gréacháin	Grehan, Grimes, Graham: líonmhar: Lár na Tíre, Connachta. B'fhéidir gur ionann gréach agus scréach (= béic) ach ní mór a mheabhrú gur sloinne Albanach Graham i gCúige Uladh agus go mbaineann Grimes le Ó Gormaile, leis. In ndeireadh na dála, is féidir le muintir Grehan a rá gur Gréachánaigh iad gan aon agó.
