I am writing thank you notes for wedding gifts and I am using my guest list, and the list of gifts with the names of the guests of who gave them as reference guides. I have come across relatives (one couple) who did give a card but their names are not on our gift list. I cannot remember if they gave us a monetary gift or not. I have been mentioning specific gifts in cards I have written to every other guest, so how should I word this one? Thank you for any advice!
