I’m looking for some new options, so any ideas would be great, thanks 
Also, do you think any of these names are usuable for a boy?
[name]Rex[/name]
[name]Ambrose[/name]
[name]Boone[/name]
[name]Darcy[/name]
*Not pregnant, just looking at names.
[name]Just[/name] how vintage are we talking about here?
[name]Alaric[/name]
[name]Albert[/name]
[name]Amos[/name]
[name]Arthur[/name]
[name]Constantine[/name]
[name]Cornelius[/name]
[name]Dexter[/name]
[name]Edgar[/name]
[name]Frederick[/name]
Godric
[name]Howard[/name]
[name]Leonard[/name]
[name]Ludovic[/name]
[name]Oliver[/name]
[name]Oscar[/name]
[name]Oswin[/name]
[name]Nicodemus[/name]
[name]Percival[/name]
[name]Russell[/name]
[name]Samuel[/name]
[name]Theodore[/name]
[name]Thomas[/name]
[name]Walter[/name]
I’d say [name]Rex[/name] is usable, as is [name]Boone[/name]. I don’t think [name]Darcy[/name] or [name]Ambrose[/name] would sound masculine enough these days.
I think all the names you listed are usable. I absolutely love them all but [name]Darcy[/name], that’s just not for me, but [name]Rex[/name], [name]Ambrose[/name], & [name]Boone[/name] are amazing!
Some others
[name]Cyrus[/name]
[name]Chester[/name]
[name]Silas[/name]

[name]Malachi[/name]

Oops we posted at the same time so sorry for repeats!
I love [name]Rex[/name] 
[name]Desmond[/name] also comes to mind
To me ‘vintage’ means old but no longer in style. See here
Names like:
[name]Clarence[/name]
[name]Ernest[/name]
[name]Herman[/name]
[name]Marlin[/name]
[name]Harvey[/name]
[name]Edgar[/name]
[name]Chester[/name]
[name]Harold[/name]
[name]Clifford[/name]
[name]Horace[/name]
[name]Alvin[/name]
[name]Wilbur[/name]
Others are old but definitely gaining in popularity if you go by how much they are seen around NB:
[name]Everett[/name]
[name]Warren[/name]
[name]Arthur[/name]
[name]Rufus[/name]
[name]Harrison[/name]
[name]Willard[/name]
[name]Roscoe[/name]
[name]Harley[/name]
Here are some more ideas.
[name]Harmon[/name]
[name]Elias[/name]
[name]Wallace[/name]
[name]Vernon[/name]
[name]Harlan[/name]
[name]Vance[/name]
[name]Archibald[/name]
[name]Edwin[/name]
[name]Lyle[/name]
[name]Basil[/name]
[name]Milo[/name]
[name]Gordan[/name]
[name]Eldon[/name]
[name]Lloyd[/name]
[name]Thaddeus[/name]
[name]Bartholomew[/name]
[name]Ellis[/name]
[name]Orson[/name]
[name]Darwin[/name]
[name]Gilbert[/name]
[name]Walden[/name]
[name]Leroy[/name]
[name]Stanley[/name]
[name]Baxter[/name]
[name]Harvey[/name]
[name]Wilbur[/name]
[name]Roland[/name]
[name]Eugene[/name]
[name]Clyde[/name]
[name]Kirby[/name]
I like [name]Rex[/name] and [name]Ambrose[/name] a lot. [name]Darcy[/name] is very feminine, and [name]Boone[/name] just makes me think of the dimwit character from Lost.
I like these suggestions: [name]Rex[/name], [name]Boone[/name], [name]Oliver[/name], and [name]Harrison[/name]… I don’t really like [name]Ambrose[/name] because to me it sounds like [name]Amber[/name] [name]Rose[/name] which is definitely not a guys name.
I think all of the names you listed are useable. I’ve only heard [name]Ambrose[/name] pronounced AMbrohss, which is different enough from AM-bur ROHz (or AM-beh ROHz) that it isn’t an issue.
[name]Darcy[/name] ([name]Darcie[/name], [name]Darcey[/name]) is a fairly popular female name in the UK at the moment, but the immediate association with Mr [name]Darcy[/name] from Pride and Prejudice, and in [name]Canada[/name] with father of Confederation D’Arcy [name]McGee[/name], mean that it’s definitely still on the table as a male name.
Vintage- not quite sure what you’re looking for here, but I’m thinking model-Ts and bowler hats:
[name]Wilfrid[/name]
[name]Bertrand[/name]
[name]Percy[/name]
[name]Gerard[/name]
[name]Francis[/name]
[name]Alfred[/name]
[name]Edwin[/name]
[name]Humphrey[/name]
[name]Archibald[/name]
I think they’re all useable except [name]Darcy[/name].
