Is it just me?

My boyfriend and I have been dating for a while. He is really close with his family has two brothers and one sister. They grew up rich like...really rich. They all know how to fight they all had extra money to do curricular activities. I think that is super cool and would think anybody would love to be able to ride horses or have dozens of dirt bikes and four wheelers or have someone teach you to sing and play piano. That being said my boyfriend has been talking about his sister alot lately like how she is perfect and a goddess among women which I'm like okay yea she is a nice girl no harm done right ? Well today we were talking about having a baby and if it were a girl what the name would be...and surprise surprise he wants to name our girl after his sister....how would you guys handle this situation ?
