I absolutely love vintage names, however I can’t find many unisex ones that I like… Any ideas??? 
I think some vintage nicknames can be considered unisex - [name_u]Teddy[/name_u], [name_u]Frankie[/name_u], [name_u]Kit[/name_u] etc.
[name_u]Noah[/name_u]? I think it is listed on NB as unisex
Sophio ? I remember seeing this name listed on some Wicca name list and I love it, I think despite the o ending it could be unisex
[name_u]James[/name_u]
[name_u]Micah[/name_u]?
[name_u]August[/name_u]
[name_u]Emmett[/name_u]
[name_u]June[/name_u]
[name_u]Vivian[/name_u]
[name_u]Lou[/name_u]
[name_u]Vinnie[/name_u]
[name_u]Georgie[/name_u]
[name_u]Jem[/name_u]
[name_m]Pip[/name_m]
[name_u]Kirby[/name_u]
[name_u]Nat[/name_u]
[name_u]Mo[/name_u]
[name_u]Marian[/name_u] was the first thing that came to mind.
[name_u]Billy[/name_u]
[name_u]Georgie[/name_u]
[name_u]Freddy[/name_u]
Hm, back in the day only nicknames were truly unisex (apart from a few names like [name_u]Evelyn[/name_u], [name_f]Alison[/name_f], etc.) and ones names were used for girls ([name_u]Leslie[/name_u], [name_u]Courtney[/name_u], etc.) they weren’t used for boys anymore.
I have two lists of vintage nicknames on my blog (the 4/50 link), there are quite a few that were in the Top 1000 for boys and girls, for example:
Bennie
Bertie
Bobbie / Bobby
Artie
Bonnie
Callie
Carrie (maybe Cary / Carrie)
Eddie (maybe Ettie / Eddie, depending on your accent)
Hallie
Sammie
Ollie
Jodie
Not already mentioned:
[name_u]Ellis[/name_u]
[name_u]Jessie[/name_u] / [name_u]Jess[/name_u]
[name_u]Lee[/name_u]
[name_f]Pearl[/name_f]
[name_u]Elliot[/name_u]
[name_u]Charlie[/name_u]
[name_u]Madison[/name_u]
[name_u]Evelyn[/name_u]
[name_u]Meredith[/name_u]
[name_u]Evelyn[/name_u] & [name_u]Meredith[/name_u] seem very feminine to me but are historically unisex
[name_u]Angel[/name_u]
[name_m]Julian[/name_m]
[name_u]Logan[/name_u]
[name_f]Braylee[/name_f]
[name_u]Dakota[/name_u]
[name_f]Rose[/name_f]
[name_u]Billie[/name_u]
[name_u]Bobbie[/name_u]
[name_u]Charlie[/name_u]
[name_u]Phoenix[/name_u]

And [name_u]Lake[/name_u]
