Sibling for Henrietta and Matilda

[Mum2B36]

We have a Henrietta (Hettie) and Matilda (Tilly), they are mostly known by their nicknames, apart from at nursery. Any ideas for a name for their sibling (gender unknown). Thanks so much.

Henrietta and Matilda both make me think of queens. So Adelaide, Elizabeth, Victoria, Alexandra, Philippa, Guinevere, Caroline for girls?

Henrietta, Matilda and Clara

Henrietta, Matilda and Quentin

Beatrix or Beatrice

How about a heavy hitter like Gertrude or Agatha?

How about Louisa for a girl & Wilfred for a boy?

—so cute nn options like your current DDs Hettie & Tilly
Lou or LouLou and Wilf or Fred/Freddie

Evelynn Evie
Florence Florrie
Charlotte Lottie
Constance Connie

George
Emmett
Lucas

Julian
Orlando
Peter
Maximilian (Max)

Rowena
Eleanor
Beatrix
Constance

Thanks everyone. I like Evenlyn/Evie a lot but I am a bit worried about how popular the Evie/Ava etc names are. I do really like Florence so I think this may be the favourite so far. Thanks all.

Boys we are really unsure about but perhaps that's because we can't visualise a boy at the moment.

Samantha
Brianna

You seem to have picked up the vibe of Roald Dahl that the OP has in her name choices.
