I love the name [name_m]Oliver[/name_m]. Here are my top three names for his possible sister.
1 [name_f]Lucy[/name_f] - has the same spunky vibe as [name_m]Oliver[/name_m]!
2 [name_f]Penelope[/name_f] - [name_u]Penny[/name_u] and [name_f]Nell[/name_f] are wonderful nickname options
3 [name_f]Sylvia[/name_f] - has the same antique charm as [name_m]Oliver[/name_m].
I love [name_f]Violet[/name_f]/[name_f]Violetta[/name_f] with the nickname [name_f]Lottie[/name_f]. I also like [name_f]Penelope[/name_f] and [name_f]Amelia[/name_f], but ultimately voted for [name_f]Violet[/name_f]. Good luck!
I picked [name_f]Lucy[/name_f]. [name_f]Millie[/name_f], [name_f]Ellie[/name_f], and [name_f]Lottie[/name_f]/[name_f]Lettie[/name_f] are too much like [name_u]Ollie[/name_u].
I can see why you’re having a hard time choosing, they’re all so gorgeous! The only one I would not recommend is [name_u]Everly[/name_u] with [name_m]Oliver[/name_m]. They are a bit of a tongue twister and matchy matchy together. I think the other ones with the letter V in them coordinate better with your son’s name. [name_f]Penelope[/name_f] shares that o sound which makes it a complementary set. [name_f]Lucy[/name_f] has the same vintage charm as oliver. I’d be more inclined to pick one of those names before [name_f]Amelia[/name_f] because [name_m]Oliver[/name_m] and [name_f]Amelia[/name_f] are also a few little tongue twisty together, but it’s not too much.
My top three would be [name_f]Lucy[/name_f], [name_f]Penelope[/name_f], and [name_f]Eleanor[/name_f].
I picked [name_f]Amelia[/name_f] since like [name_m]Oliver[/name_m] it’s three syllables and the nickname of [name_f]Millie[/name_f] suits his nickname of Oli.
All of yours names would go good with [name_m]Oliver[/name_m] except for [name_u]Everly[/name_u]. It’s not in the same style and looks odd next to them. I wouldn’t do [name_f]Eleanor[/name_f] either if [name_m]Oliver[/name_m]'s nickname is Olllie though because [name_f]Ellie[/name_f] is a popular nickname for it.
I voted for [name_f]Amelia[/name_f], not because it is really my favorite, but because I love the nickname [name_f]Millie[/name_f] with [name_m]Oliver[/name_m]. If I were to pick on given name alone, I would have picked [name_f]Penelope[/name_f].
