Pretend that a couple you know are expecting B/G twins. They plan to use either [name_u]Jude[/name_u] or [name_m]Luke[/name_m] for the boy, but they have absolutely no ideas for the girl. What names would you suggest?
With [name_u]Jude[/name_u] and [name_m]Luke[/name_m], I like simple but sweetly feminine girls’ names.
[name_f]Ava[/name_f]
[name_f]Grace[/name_f]
[name_f]Calla[/name_f]
[name_f]Ivy[/name_f]
[name_u]Brooke[/name_u]
[name_f]Lily[/name_f]
[name_f]Kate[/name_f]
[name_f]Tess[/name_f]
[name_u]Clare[/name_u]
[name_f]Esther[/name_f]
[name_f]Rose[/name_f]
[name_f]Lucy[/name_f] (with [name_u]Jude[/name_u] only)
[name_f]Blythe[/name_f]
[name_f]Dinah[/name_f]
[name_f]May[/name_f]
[name_f]Fern[/name_f]
[name_u]Jael[/name_u]
[name_f]Ruth[/name_f]
[name_f]Eva[/name_f]
With [name_m]Luke[/name_m]: [name_f]Aurora[/name_f], [name_f]Clara[/name_f], [name_f]Gwen[/name_f]
I second the names [name_f]Rose[/name_f], [name_f]Lucy[/name_f], [name_f]May[/name_f], [name_f]Ruth[/name_f], [name_f]Grace[/name_f], [name_f]Claire[/name_f], and [name_f]Ava[/name_f]. The girl’s name should be short and clean, a bit common. I suggest [name_f]Zoey[/name_f], [name_f]Mae[/name_f], [name_f]Pearl[/name_f], [name_f]Violet[/name_f], [name_f]Ella[/name_f], [name_u]Avery[/name_u], [name_f]Jane[/name_f] (with [name_m]Luke[/name_m] only), [name_f]Mia[/name_f], and [name_u]Piper[/name_u].
