My sister is [name_f]Caroline[/name_f] and she has a daughter named [name_f]Jane[/name_f]. Other names in our family that I think work well with these two are [name_f]Lucy[/name_f], [name_f]Charlotte[/name_f], [name_u]Sam[/name_u]/[name_m]Samuel[/name_m].

[name_f]Jane[/name_f] [name_f]Elizabeth[/name_f] & [name_f]Caroline[/name_f] [name_f]Claire[/name_f] are very classic choices. Understated and feminine but unexpected personally I don’t know any baby [name_f]Janes[/name_f] or Carolines.
