My son Patrick Caleb Shields has just had his first son is naming him "Patrick Caleb Shields II". I know that traditionally his name should be Patrick Caleb Shields,jr - but his father & mother do not care for "jr". I hate to break the rules, but I care more for keeping the peace. Is it ok for the baby to be refered to as Patrick Caleb Shields II or does that confuse the lineage?
