Lindsay and Meredith are two that come to mind, as well as Ysaie - not actually a featured name here on Nameberry, but actually the (possible) name of one of Tristan and Iseult's sons (along with Marc, rather oddly...not necessarily a sibset I would have chosen myself). Actually, I haven't heard anyone try to use Ysaie as a girl's name, but in the few pree-Googling minutes before I knew it was masculine, I assumed it was a girl's name. I don't know why, but I have learnt my lesson now, and will try not to pre-judge again. :)
What a good thread topic!
I'm going with Ariel (Disney movie boo!). Very commonly given to boys among Spanish-speaking parents (it's 78 in Chile) but obviously given much more to girls. I like it better on a boy anyway.
Wanted to edit to add that the MALE mayor of Providence, Rhode Island is named Angel.
Ariel, Darcy, Marion, Meredith & Vivian.
Jules and Robin also, but here in England I'd say they are more male anyway.
I haven't read the whole thread, but I'd like to add Addison, Harper, and Bailey to this list! I would say Avery, too , but its been mentioned already.
I'm prepared to be tr and feathered, but If we were doing one of these for the girls, I would add Jasper to the list. It has a similar sound to Vesper, Harper, Esther, etc., and if Ruby and Pearl are feminine, why not Jasper?
Sorry for repeats, but here's my favorites.
Evelyn: not everyone knows this used to be for boys! I think it's really dashing, when pronounced like EVE-lyn.
Shelby: this is actually my own name. I've met one boy called Shelby, and I though it was so handsome!
my fave boy names that have gone to the girls:
Jordan, Courtney (Court... it used to be a male name), Sasha, Skyler, Shelby, Avery, Bailey, Riley, Finley, Finn, Emerson, Elliott, Hunter, Fallon...
*Kerry! e.g. Kerry Drake, a comic strip I loved as a kid.
*Leslie e.g Leslie Nielsen
*Evelyn, my daughter's name, can also be used as a boy's name, though very rarely these days.
*Aubrey (another vote for Aubrey). I've met a male Aubrey and he was very elegant, yet totally masculine.
Brittney (historically male or not, wouldn't THAT be a bold choice today?)
Lindsey (DH has an uncle Lindsey!)
... I'm sure ill think of more as the day wears. I don't know if it's fair or not but these have always bugged me to no end. I feel parents should be able to name their kids whatever they want (heavens knows my siblings and I are prime examples with a female Bergen, and male Seneca), but the pool of "appropriate" boys names is shrinking as "girl" names aren't making the cross back over.
All this, of course, has already been discussed thoroughly.
