We've come up with a couple of names but OH thinks we need a joining name, but we're debating where it's needed. The other two have two middle names too so we want to keep with the trend. So far we have:
Carys __ Samantha
or
Carys Samantha __
Carys was the name that jumped out at us from the Office of Statistics spreadsheet and also one Mum had previously mentioned when we were talking about names. Samantha is his (grown-up) niece's name. She's the person we're probably closest to in his family and we've given the other two names that honour someone so she was the one person we felt we had left to honour and they go well together.
