I am Irish and quite keen that my child will have an Irish name. My own (Irish) name does not sound like it is spelled and a lot of people in the UK struggle with it, so I want to give our DS an Irish name that most people can manage. The middle name will be Patrick. It was both of my grandfather's first names, it is my DF's middle name and my DB's middle name, so DH and I are quite keen for that tradition to continue.
I'm not a fan of Killian with a K, and prefer Cillian (which is pronounced the exact same way).
