Sorry for long title!
Annie is on our list on of girls' names and it's a fave because DH and I both agree on it (unusual!), we don't know any other children called it and it goes well with our surname - result!!
Except that one of my friends's also loves the name and I know if she had a daughter she'd definitely pick it. She's been saying so since school (and we are now both approaching 35!). The thing is she doesn't have a partner and I'm not sure how likely it is she'll ever have kids. Is this relevant? If we use it, will we have "stolen" her name? Can you even "steal" a name"?
