A sibling for Alexander & Sebastian?

[AlexSebandOi]

Any ideas on what you'd call a lttle brother or sister for Alec & Seb?

longer names or a similar syllables seem to flow better than Bob & Mary;
Benedict, Gabriel or William and Catherine or Vivienne are no goes but the style I'd like so I'd say I like classic/slightly poncey.
dh likes 'normal' less frilly names (Henry, James, Rebecca etc, he hates Benedict)!

I instantly thought : Joshua

It sounds like it's from the same "pack" and it shortens the way the others do as well.

Tristen

Rory

No idea for girls names...

Beatrix, Miriam, Tabitha, can't think of any boys!

Alastair
Jeoffery
Gregory

Elizabeth
Georgina
Roberta

Argh, typed out a massive reply & internet are it!

Is Camilla too associated with 'her'? I've always loved it but not sure if I'd use it?

Congratulations on your recent arrivals (& fab name choices) Piglet!

Love Arabella, Fredrick...Jennifer, hmm will have a think!

Christopher or Hugo
and
Adelaide or Charlotte - Miranda and Camilla are also fantastic.
