Reuben, Rigby, Romero, Royce (I have a baby names book that goes alphabetical & split into girl's names & boy's names. It's got the meanings too)
Rylan, Ryker, Ragnar, raugust,
Roman, rusty, Remy, Reed, rory
I have a son called Reece, it's not an unusual name but I wouldn't say it's very common.. Well it's not in my area, he's the only Reece at his school x
