Twin sister for Thomas?

[Treaclemine]

She's fictitious, but hates being Thomasina. She want's a name of her own.

Geraldine

Gerry, shirt for Geraldine. Of course.

X post damnit. Plus a typo from me 😆

My sister was very nearly a Thomasina until my uncle got in first and named his son Thomas.

Matilda … Tom and Tilly

Teresa would be lovely even though the Maze Runner connotations would ruin it a bit.

Also considering she wants her own name, she probably doesn't want the same initial. How about

Lucy
Isabel
Rose
Audrey
Freya
Lydia

Katie

Tamsyn (which is a variant on Thomasina).

Charlotte

Tiny
Topsy
Tuppence

Rebecca

Tamasin

Thank you for the ideas. On line there are very few girl's names which like Thomas , mean twin.
Tiny, Topsy and Tuppence are going to grow up! Freya is too pagan. I was very taken with Tabitha,but there is the T. Rebecca I have a friend so might do, but Matilda is of period. Did you know Rebecca means binding?
