Nice family. I have to use
Cormac in the Sims too because the meaning is too unfortunate to consider using it in real life.
For the next kid, how about
Ciaran or
Darragh for a boy, and
Roisin or
Mairead for a girl?
There must be something in the water in my Sims neighborhood because for awhile everyone kept having twins. It was getting annoying. :)
