I can think of a few examples that transition kind of easily - like [name]Sydney[/name] is a great example. Not sure when it came into vogue (or was ever really too popular), but at some point, it seemed cute on a girl even when it was an old man kind of name, and now unusable on a boy, [name]Sid[/name] the [name]Science[/name] Kid, notwithstanding. That’s a weird show.
[name]Bailey[/name] is another one I’d bring up - although most consider this name a boy’s name that the girls “stole,” it was pre-emptively stolen. It was out of use for boys for a long time and emerged on the girls side in the 1983, not on the boys’ side until 1992, and has in the current era, been a lot more popular on a girl than a boy by hundreds of rank points. I think we are in a time where a lot of names ending with -ley like [name]Stanley[/name], like [name]Bailey[/name], and like [name]Ashley[/name] and [name]Shirley[/name] before them start to slide over to the girls side.
I really think it is subjective, but a lot of trends (or name talk here) point to the feminized form of a male geezer name instead, names like [name]Bernadette[/name], [name]Henrietta[/name], [name]Harriet[/name], maybe even for some, [name]Geraldine[/name], [name]Ernestine[/name], [name]Edwina[/name]. [name]Georgia[/name] and [name]Georgina[/name], as well as [name]Josephine[/name] ([name]Joseph[/name] is not a geezer name so much, but [name]Josephine[/name] kind of is antiquated revival), and [name]Philippa[/name] are some of the more accessible names we are considering. [name]Haven[/name]'t heard anything about [name]Clementine[/name] in a while, but [name]Clem[/name] kind of associates with men of a certain oldness, as well as [name]Sally[/name]/[name]Sal[/name], and other masculine nicknames from feminine names like [name]Frankie[/name] for [name]Francesca[/name] or [name]Charlie[/name] for [name]Charlotte[/name].
I think for the “cutting edge,” they might take a name that really just sounds appropriate for a girl (to them), or different, out of vogue altogether, and they probably won’t get too much approval from the forum posters. They know they are being outrageous, so if that’s what they want to do, I don’t think names like [name]Harold[/name] or [name]Floyd[/name] will become that popular for a girl just because someone thinks it’s neat to name their daughter that.
