Tabitha's sister is called

[Balonzette]

Magdalena
Theodora
Genevieve
Esther
Anneliese
Rosa
Josephine
?

I like Esther, Anneliese & Rosa most from your list (although they're all lovely names). My first thought when I saw your thread title was Elodie.

Theodora

Jeanette nn jeanie

My Tabitha's sister is called Genevieve (genie).

Esther

How about Jacinta?

Harriet

Antonia

Genevieve came to mind before I opened the thread!

Well, Ginny. But same.

Rosalind
Marianne
Juliet
Marnie
Lotta
Camilla

Rosa is gorgeous, my favourite from your list. Maybe Rosalind is you like something longer. I always think Jemima sounds good with Tabitha.

Thomasin

Matilda

Love Josephine & Esther

Don’t mind Theodora & Rosa (but would much prefer Rosalind)

Not keen on Magdalena, Genevieve or Anneliese

How about
Clementine
Beatrice
Catriona (mostly because I’d love the idea of Tabby & Cat )

Hester as an alternative to Esther?

Emmeline

Esther is my favourite

Matilda came into mind straight away. From your list I think Rosa is beautiful ⚘

If (BIG if!) we have a third Tabitha’s sister would be Clemmie/clementine

Genevieve!

I LOVE Clementine but I don't think I'm cool enough to pull it off!

Matilda is beautiful but I just seem to know so many little Matildas.

Jemima is lovely but can't get DH on board.

Beatrice/Beatrix also a fab name but Tabitha gets called Bea by the small children in the family who can't say her name easily and it's stuck a bit!

Lotta is also a really cool name, but when I Googled it, it said the meaning was 'manly' and while I don't usually worry too much about meanings, I don't think she'd thank me for that one!

Actually I also love Harriet. Hattie is so cute!

This thread has made my decision harder

Scarlett?

Another vote for Harriet here!

Or Rosa from your suggestions

Tabitha's brother is Theodore.
So I like Theodora.

I also like Esther.

Genevieve or Josephine. Love Isobel with Tabitha too.
