I have a little Ronnie. DP picked it and I'll admit I wasn't sure at first and took me a few days to agree after he was born, but it really suits him. He looks like a Ronnie. I was actually thinking earlier none of the names I liked would've suited him. I am a fan of waiting to see what babies look like before naming them though.
The Kray association doesn't bother me in the slightest and the 2 Ronnies are cool. It's easy to say and not at all popular in my area, although is top 100 so must be popular in other areas
