Ways to honour grandparents without giving baby their names

I just made a post talking about how it’s very important on my fiancé’s side of the family to honour elders of the family by giving the kids their middle names. I personally just don’t want to do this. My fiancé doesn’t feel super strongly about it himself either. And quite honestly, I don’t really like them enough to name my baby after them 😂

I’m just wondering if there are other ways people can think of to honour the grandparents of my baby without giving her their name. I’m stumped. I feel like his mom especially would feel very hurt if she wasn’t honoured in some way.
