Choosing a 4th name

[4babyboysbrewing]

We are expecting our 4th baby boy in 1 month and finding it really hard to choose a name. We already have a Charlie, Chester & Rupert but can't decide on the 4th??
Should we keep to a name beginning with 'R' or go for a different letter?
We're not keen on modern names, these are the latest but any other suggestions would be much appreciated xx
Henry- maybe a bit common
Hector- alternative to Henry but would have to be brave!
Arthur- like
Woody-don't know if it goes
Ernie-cool
Robbie
Reg
Angus
Burt
Who ever thought choosing a name would be so difficult!!!

I like Rex but can't use it as a family member has it so I thought reg instead but everyone I tell says it's too townie for my other names.
Maybe I should stop asking people!!!

Rhett.

Youngest of four he'll have to assert himself. Something epic like Hector, Magnus or Titus.
