Thank you for the clarification, I thought Rodrick sounded to much non Celtic, but then again so does Roldophus, which still puzzels me. Its origin apears Roman, and shows up in Dutch and English names, and one Irish Viscont. And Yet I found it on a number of Irish baptismal records during the 1860 & 70's. i know there was an Irish Bishop of Armagh with that name as well. Or maybe it to was anglicized. I think I would prefer Rory over Rody.
Thanks again.
