We received a gift before our shower, and I want to get the thank you note(s) done as soon as possible. Here's the situation: the gift giver(s) couldn't attend the shower, so they sent the package to my parents's house. My mom couldn't stand having it in the house, so she made FI pick it up and take it to our place. When I opened it, there was only one name as the gift giver (my mom's cousin) listed on the slips. There was no gift receipt/card/etc inside.
My dad said he thought the gift was from 5 of my mom's cousins and her aunt. I only have one name on the slip. I don't want to leave anyone out of thanking them, so what should I do? My mom at the time refused to find out who went in on the gift (if at all), and she is still refusing to do so.
