Middle name for baby

My Husband and I have been going back and forth with middle names for our daughter . Her first name is Lilian / lily . Our choices for her middle name were grace, Mae , and rose . His mom would “joke” about then name fern because thats her middle name . Well she wasn’t going so good last week and after a not so great phone call my husband asked what I thought about giving the baby his moms middle name . At the time I was thinking absolutely not , I didn’t tell him that. I don’t really like that name and I wanted to name my baby what I wanted and not feel guilted or pressured into giving her a name I didn’t like. He didn’t even like it and his mom doesn’t even like it . However on Sunday night she ended up passing away suddenly so now I feel it may be more Important and would mean more to my husband if we did give her a middle name after his mom. They were very close and he keeps kinda making comments about the name fern. As much as I didn’t want too use it I feel I should get over it and use it because it would mean a lot to my husband and I want him to be happy . But my sister did make a good point that maybe we can give her 2 middle names . So one I want and then one after his mom. Her first name is Donna so I was thinking either dawn or fern . But I feel the only name that fits would be Mae . Rose is out because that’s 3 plants lol.

I know it’s our choice at the end of the day but could you ladies tell me what you think sounds best!! Thank you 💜
