We are sending announcements to those not invited so I'm not sure if the addressing still has to be 'formal.' But how do I address one to a widow? If details matter: the husband passed away 3 years ago and to my knowledge she isn't dating. I also got an invitation to her daughter's wedding and her return labels where just her first and last(married) name. So I couldn't get any clues there either. So should I go ahead and use Mrs. or just Miss? Or would it just be better and safe to just lable it her first and last name? I feel like using Miss would put lemon on the wound. But so could using Mrs.
