Cool sibset. The names' styles suit each other. I didn't notice the "nic" similarity until you said it. I don't think it would be noticeable enough to matter, especially since a
Dominic would more likely be called
Dom than
Nic. But since I've noticed it and do not personally care for
Dominic, I would use or suggest the names for someone's sibset.
