Name suggestion?

This might be long and I apologize in advance, but please read. Me and my boyfriend are having a baby girl. His father passed away this past March in a car accident. His name was Carl & I would really like to have something similar to that for a first name.. I don’t like Carly. Too original.. His middle name was Robert if someone can make something out of that. rather than Roberta. Thank you so much in advance. I would love to do this for him. I’ve been thinking so hard and can’t come up with anything. her middle name will be Michelle. after his step mom who raised him. Thanks everyone.
