DH won't let this name drop. I've been resistant to it as I assumed it was German in origin (and we're not German) but I've just looked it up and it is an old English name, which has made me reconsider.
It looks like Ranulf is the more usual spelling but Ranulph (Fiennes) is better know.
So what are your thoughts on this one? Too out there? I've never heard of another other than Fiennes.
Other names on the list are Sebastian, Austin, Joseph, Laurence...
