Relatives that have passed

That is sweet of you. a lot of people do things that remember loved ones. for instance they have a table with photos or they leave empty chairs symbolizing their presence, etc.

Many people do a memorial table at the ceremony with pictures of loved ones who have passed. Some people also setup a place setting at a reception table to honor them.

A photo in a pocket watch? Some people make display tables with signage and others choose to do something private such as a photo in a locket or carrying something that reminds them of the relative who passed on without making a focal point.

Maybe a candle burning in front of a framed photo

I am a huge fan of carrying something that reminds him of the person. I would check with the cousin's immediate family before doing anything more visible/public to be sensitive to their emotions. My family tends to steer away from photos or other visible reminders of our passed relatives because we react too emotionally to reminders. Example: at a recent wedding of mine, someone brought out a picture of my passed uncle. Two family members started crying, and soon there were no less than 12 family members huddled crying *in the middle of the reception*. It was just too raw for that kind of reminder

I really wanted to do a table with pictures for my fiancé’s parents who have both passed when he was younger but he doesn’t want me to 😔 he doesn’t want want to be reminded of something sad on a happy day

I’m so sorry for your fiancés loss. If he is wearing a flower on his suit/tux you can have the flower be the color of the cancer he passed away from. It will be close to his heart and a nice way to remember him by
