As for the spelling, seems it's definitely Katherine, not Katharine. Makes me feel easier, thank-you, knowing the opinion on spellings on here...
I like Rebecca, it's just that I've known too many ditzy ones. Not unintelligent, just... not the most sensible people I've ever met. I'm not saying that by using that name I'll be consigning my DD-to-be to a life of Bridget Jones-dom, but with the genes she's inheriting I don't want to risk it. All you Rebeccas who've been kind enough to post, what do you think?
Georgina could become Georgiana, or is that a bit too erghhh? That's about as wacky as I want to go!
