festive family Christmas card, mystery people

I purchased a box of assorted vintage postcards at an antique shop in Indiana and was delighted to find this Christmas card mixed in. Now that’s a family photo! There is nothing on the back other than some yellowing from age, so sadly Fred, Bettye, Freddy, and Pat are mysteries to me. I know it’s a long shot, but I would love to find these folks or their descendants to share this card with them. If anyone sees names that ring a bell, let me know. For now they are spending a merry Christmas on display in my home.
