[name_m]Theodore[/name_m] & [name_f]Diana[/name_f] and [name_m]Theodore[/name_m] & [name_f]Daphne[/name_f] are probably my favorite possibilities but I also like:
[name_m]Theodore[/name_m] and [name_f]Violetta[/name_f]
[name_m]Theodore[/name_m] & [name_f]Adelaide[/name_f]
[name_u]Elliot[/name_u]/ [name_u]Elliott[/name_u] & [name_f]Adelaide[/name_f]
[name_u]Elliot[/name_u]/ [name_u]Elliott[/name_u] & [name_f]Frieda[/name_f]
[name_m]Lucas[/name_m] & [name_f]Daphne[/name_f]
[name_m]Lucas[/name_m] & [name_f]Violetta[/name_f]
Yes [name_f]Barbara[/name_f] is probably a bit dated still but I have started to see people considering it again. I don’t think it’s unusable. I’d probably be more inclined to use it as a middle, but only because there are other names here that I like more. I think it would work nicely as a middle for [name_f]Daphne[/name_f] or [name_f]Adelaide[/name_f] especially.
My favorites from your girl names are [name_f]Adelaide[/name_f] and [name_f]Viola[/name_f], from your boys I like [name_m]Theodore[/name_m], [name_u]Everett[/name_u], and [name_m]Elijah[/name_m].
Adelaide & [name_m]Theodore[/name_m] is my favorite combo. They sound noble. [name_f]Addie[/name_f] and [name_u]Theo[/name_u] are cute nicknames.
Violetta and [name_m]Elijah[/name_m]
[name_f]Adelaide[/name_f] and [name_u]Elliot[/name_u]
[name_f]Margaret[/name_f] and [name_m]Theodore[/name_m]
[name_f]Daphne[/name_f] and [name_m]Lucas[/name_m]
[name_f]Alina[/name_f] and [name_u]Everett[/name_u]
I like [name_f]Adelaide[/name_f] & [name_u]Elliott[/name_u] together. I’ll also suggest [name_f]Adelaide[/name_f] & [name_m]Arthur[/name_m] (usually i say no for twins sharing the name first letter of their names, but I think those work well together and the “A” sounds a bit different).
Love [name_f]Violetta[/name_f] ([name_f]Viola[/name_f]) & [name_m]Theodore[/name_m] ([name_u]Theo[/name_u]). Though [name_f]Violetta[/name_f] seems a bit more unique than [name_m]Theodore[/name_m], what about Theodin/Theoden?
I also like [name_f]Barbara[/name_f]. It may be a bit dated… but not unusable! I mean, come on [name_f]Barbara[/name_f] Streisand is amazing!
I’ll suggest [name_f]Deborah[/name_f] (nn [name_f]Debbie[/name_f]).
