Thank you card- after someone has passed

All you can do is address it to her, and make some reference to your condolences on her loss.

I agree with the last post. I would address it to just her. But give your condolences and that it was great seeing him at the wedding.

I would also purchase a condolence card and send.

Separately, send a Colleen letter or card, , to your aunt. If you have any mention of some special memory of the two of them, or just say you are sorry for her loss, that is something she may read now, or again later. Address the thank you only to her, but mention how nice it was to see "you and ______" at your wedding.

!!!autowrite. A condolence letter or note
( Which the phone insists is a conference or a Colleen!)
