Help! I invited my dad's cousin and husband to the wedding and addressed it to just them, not "and family", but they have 4 as the number of guests attending. I don't even know these people, but my dad wanted to invite his cousins out of courtesy because he has been invited to their children's weddings. I asked my dad about it and told him the names on the invite and he only recognized his cousin's name. What should I do? We didn't plan on these extra invites.
