[name_f]Serafina[/name_f] [name_f]Pearl[/name_f] fits the vibe better, in my opinion. 
Also, I have no idea if it’s dealbreaker or even well-known, but [name_f]Barbara[/name_f] [name_m]Roberts[/name_m] is Barbie’s (as in, the doll/character) full name. [name_m]Just[/name_m] thought you might want to know!
