I understood it to mean names that you wouldn't use nicknames for, not names that there aren't nicknames for.But if I misinterpretted, then I would swap Patrick for Ciaran and Mary for Effie. It was close between those two anyway.
I meant names that others couldn't use for your kids (or your kids change them later on and then you have to call your child by a name you hate -like Sam for Samuel in my case). So, Patrick is definitely out, but Ciaran is great:-)
