Baby names?

So I have a while before I am actually to know the gender of my little baby(I’m only 5 weeks 5 days), but my husband and I wanted to pick a baby name for a girl that would incorporate my husbands first child to our baby. Really long and depressing story made short, my husband lost his daughter on her 4th birthday(they share the same birthday as well) due to a 17 year old kid who had family issues and he got drunk and high and decided to drive... I feel like it would hurt every time we said the name. I am very lost and extremely conflicted
