First, I must say well done! Your other children’s names are absolutely BEAUTIFUL! [name]Theodore[/name] is my favorite boys name, as well, and I love how you got [name]Nate[/name] from [name]Ignatius[/name] (that’s amazing that you have family names like that), [name]Gwendolen[/name] is lovely, especially with the nn [name]Gemma[/name], and [name]Seraphina[/name] is positively gorgeous. Wow! I’m just speechless at such a powerful sibset!
[name]Philippa[/name], nn [name]Pippa[/name] (loved for a long time, top choice) - [name]Philippa[/name] is a stunning name! (In fact, I’d love to use it someday, but as my brother’s name is [name]Philip[/name], I’d use it as a mn.) [name]Pippa[/name] is cute as all get-out, and it sounds great with sisters [name]Gemma[/name] and [name]Sera[/name].
[name]Rosalie[/name], nn [name]Rosie[/name], [name]Rosa[/name], Row (not my fave, & worried about twilight) - Yes, [name]Rosalie[/name] is a Twilight name. However, by the time your future child is older, I seriously doubt that any of the kids are going to hear it and think “VAMPIRE!” I wouldn’t be too worried. It does also sport a lot of good nn’s. However, if you know already that this one is not a favorite, I’d just cast it off the list. Or maybe consider it as mn material.
[name]Fionnuala[/name], nn [name]Nuala[/name] (likely won’t use it because of pronunciation/spelling issues) - Although spelling/pronunciation can always be an issue, I wouldn’t worry about it that much. It seems like people are naming kids with a much wider pronunciation-range of names. And I say, as long as the spelling is legit (not Trynatee or some cringe-filled misspelling like that), go for it! This name, after all, WOULD go well with your other children. (If it helps, people quite often ask me to spell my first or last name, and in my opinion they’re pretty simple, so just because you choose an “easy” spelling doesn’t mean you won’t encounter the same problems as a “difficult” one–so if you like the more unusual name better, why not just choose that?)
Other possibilities:
[name]Octavia[/name] ([name]Via[/name], [name]Tavi[/name])
[name]Desdemona[/name] ([name]Desi[/name], [name]Demi[/name], [name]Mona[/name])
[name]Elisabetta[/name] ([name]Elsie[/name], [name]Betsy[/name], [name]Isa[/name], [name]Letty[/name], [name]Ella[/name], etc…)
[name]Adelaida[/name] (Lady, [name]Adele[/name], [name]Della[/name], [name]Aida[/name])
[name]Constantine[/name] ([name]Stan[/name], [name]Conan[/name], Costi)
[name]Horatio[/name] ([name]Ti[/name], [name]Harry[/name])
[name]Bartholomew[/name] (Barth, [name]Thom[/name], [name]Arty[/name], [name]Bale[/name])
Good luck! (-:
