My husband picked a girls name Daenerys but before we got pregnant i had told him i like the name Briana and we going to name our daughter Briana and he agreed but now that we are having a baby he says he wants a girl and wants to name her Daenerys Luna and i just added Isela in their what do yall think? Which one sounds better?
