Middle name forJack or james

[Nooneno1]

Surname is 1 syllabul we were always going to use john as middle name as both grandads called that but now its going to be jack or james we arent so keen. Original choice was Harry john, which would work but not jack john. Best friend just had a boy called harry so out of question now. Tia.

Jack was originally a diminutive of John. Register him John, call him Jack, that way you've covered your Js, then use William or Rupert or whatever you want as a middle name.
