I have an etiquette question regarding my upcoming August wedding. Both of my grandfathers have passed away this year, and I would like to honor their memories in the ceremony programs. My fiance's grandparents, however, died ten and 30 years ago. Would it only be appropriate to include all of the deceased grandparents, despite the length of time that has passed? I just want to be as respectful as possible to both families. Thank you so much!
