Hi, I have 3 sons. I have always wanted one of each, but said we would stop at 3, but decided to go for 4! We conceived a beautiful boy... It isn't a big deal, he's gorgeous and healthy! Love him to bits! Just stuck on names 
Other sons are:
Noah
Isaac
Reuben
We are Church of England, but aren't strictly religious. However, I think a religious name would go best? I love the idea of 2 syllables and 7 letters and then they all match 

I like Oliver and Elliot, but they are 3/6 letter syllables and I'd like to hunt for a 2 syllables and 7 letters...
DH likes Leo - does work with our theme, but just at the bottom! Should have used the name first
