We live in the UK, just outside of London.
We have two Children already.

Callum Bond

Clara Bond

( two CB's but we think thats enough)

We are expecting a third in the new year and would like suggestions for a new name,

My name is a long tradition to call their first born son 'James', as you can see I broke this! No desire to have another 007 ongoing joke, although it goes back eight generations!!!!
My wife's name is Amanda.

Let me know, cheers

Declan? I think it goes with your other kids names without having to have another cb

I love Clara and Callum is great too!

How about:
Callum, Clara and Aidan
Callum, Clara and Finley/Finnegan
Callum, Clara and Tynan
Callum, Clara and Quinn
Callum, Clara and Zachary
Callum, Clara and Samuel
Callum, Clara and Gareth
Callum, Clara and Daniel
Callum, Clara and Edward
Callum, Clara and Patrick

Did you want suggestions for girls names too? (I will give some anyway )

Callum, Clara and Olivia
Callum, Clara and Keira
Callum, Clara and Brielle
Callum, Clara and Paige
Callum, Clara and Phoebe
Callum, Clara and Elspeth
Callum, Clara and Rhiannon
Callum, Clara and Annabel
Callum, Clara and Genevieve
Callum, Clara and Evelyn

Maybe you could put James as an MN to honour your family tradition. My brother should have been John, then he would have been John the 5th and mum was dead against that, so she gave him John as an MN.
