My fiance and I are getting married on my mom's parent's anniversary so I really want my grandma to be escorted down the aisle and because I don't have a father my grandpa will be walking me down the aisle. I want to acknowledge that they've been together 50+ years at the wedding and just thought it would be sweet to have them both walk down the aisle, even if not together, on their anniversary.
Would it be weird/inappropriate to not have the other grandparents walked down the aisle as well?
