First name that came into my head was Eloise.

Unless Sebastian and his sister are always going to be together, why does it matter?

Eleanor

Sebastians I know have sisters called Claudia, Emma, Lucy and Sienna.
Sebastian was on my list and girls' names I loved were:
Tabitha
Cordelia
Thea
Elspeth
Miranda
Viola (not really but it would be fun to have that subset!)

Nell, short for Eleanor.

Beatrice.

Also because I know two Sebastian's and they both have a sister called Bea.

Tabitha

Jemima

Tiggy

Sebastian and Viola are twins in Shakespeare's Twelfth Knight - also in the great movie adaptation 'She's the Man'😜

Could go with Violet or Violetta instead.

Rose or Harriet (nn Hattie) or Harriet Rose

Alexandra
Louisa
Anastasia
Natalia
