My boyfriend is glued to the name Harley and I’m fine with it but we originally said Grace as middle name but lately I’ve been leaning towards Iris because of the meaning this is our rainbow baby from losing our son delivered stillbirth at 24 weeks. What you guys think?

Meaning of the name below

First name: Harley- (Jewish) mountain of God

Poss middle name: Grace- (Latin) God's grace

Poss middle name: Iris- (Greek) rainbow

Last name: Reif-nothing really found
