Sligo236: What you say is garbage. There are dozens of Norman names, as indeed Norse names, which are not English derivatives, to use your inapt phrase.

The Walshes of Tyrawley, County Mayo are held to be descended from Walynus, a Welshman who came to Ireland with Maurice Fitzgerald in 1169. This man's brother, Barrett, was the progenitor of the Barretts of Tirawley as per info by The Historical Research Center of names.com

I take acception to your not including Smith. The Gaelic sept Mac an Gabhann of County Cavan through the process of anglicisation accepted the name Smith. Except for those who retained their Gaelic surname, all other Irish names are English derivatives.

I'm Irish and I'm surprised McCarthy isn't in there as well. It's a popular name in Ireland, I'm sure it would have been 11th or 12th.
