My great aunt sent a handwritten note to let me know she can't make it to our wedding, and enclosed a check. I was in the middle of writing out a thank you card when I noticed that at the bottom, she had also signed the names of her three adult children. I think she may have done this to let me know that none of her family would be attending the wedding (although I hadn't invited the children...which I think may be the reason she declined).
Now I'm wondering if I should be sending a note to the three children as well. On the one hand, if they did all pitch in for the gift then I would want to thank each of them. But if they didn't, and especially if they didn't even know about it, I'm afraid it would come across as super weird and awkward to get a thank you note from a cousin they barely know, thanking them for a wedding gift they didn't give. So, what to do here? Will a thank you note to my aunt suffice?
