Names you consider "timeless"

I was reading the baby name wizard book and the section about timeless names sparked my interest. Basically she classifies a name as timeless if when you hear it, you don’t know if the person is one, 20, 50, or 100.
The list is diverse and spans popularity because some timeless names have been more popular than others (think [name_m]Jacob[/name_m], [name_m]Alexander[/name_m], [name_m]Samuel[/name_m], [name_m]Benjamin[/name_m], [name_u]James[/name_u], [name_m]William[/name_m], etc).
As a [name_f]Michelle[/name_f] from the 70s/80s, I now firmly have a mom name as other parents/teachers I work with have similar names that you never hear on children ([name_f]Jennifer[/name_f], [name_u]Kim[/name_u], [name_f]Lori[/name_f], [name_f]Jessica[/name_f], [name_f]Stephanie[/name_f], [name_f]Katie[/name_f], etc).
I like timeless names because I don’t want my child to have a name associated with a decade, as I do.
A couple names on the list caught my eye:
[name_u]Emmett[/name_u]
[name_u]Elliott[/name_u]
[name_f]Do[/name_f] you consider them timeless? Are they classics that are currently popular now, like [name_m]Lucas[/name_m], [name_m]Henry[/name_m], [name_m]Levi[/name_m], [name_m]Ezra[/name_m]?
Also, both [name_u]Elliott[/name_u] and [name_u]Emmett[/name_u] don’t have nicknames and [name_f]Ellie[/name_f] or [name_f]Em[/name_f] are way too femme for a boy.
[name_f]My[/name_f] son is [name_m]Charles[/name_m], nn [name_u]Charlie[/name_u]. [name_m]Charles[/name_m] is timeless which I love, I also like that there are nickname options and [name_m]Charles[/name_m] is all man, nothing feminine about it.
What other names are similar/fit that description, and what do you think of those ‘e’ names above?

I wouldn’t say [name_u]Emmett[/name_u] and [name_u]Elliott[/name_u] are timeless. I consider a name timeless if it’s been in use (if not super common, at least in use enough that people have heard of it and don’t find it strange) for at least a few hundred years. Obviously some classics are more popular than others at various times, e.g. [name_f]Elizabeth[/name_f] which is #10 in the US vs [name_f]Margaret[/name_f] which is in the 100s I think, but never fall completely out of use or off the radar.

And I’d argue timeless and classic are not the same thing- a classic may or may not be timeless, all timeless names are classics- but

I’d consider these names (among others) timeless:
[name_m]John[/name_m]
[name_m]William[/name_m]
[name_u]James[/name_u]
[name_m]Charles[/name_m]
[name_m]Alexander[/name_m]
[name_m]Edward[/name_m]
[name_m]Henry[/name_m]
[name_m]Thomas[/name_m]

[name_f]Elizabeth[/name_f]
[name_f]Mary[/name_f]/[name_f]Marie[/name_f]/[name_f]Maria[/name_f]
[name_f]Ann[/name_f]/[name_f]Anne[/name_f]/[name_f]Anna[/name_f]
[name_f]Margaret[/name_f]
[name_f]Catherine[/name_f]/[name_f]Katherine[/name_f]
[name_f]Jane[/name_f]

Can’t think of any more right now, unfortunately…

Classics. [name_m]Just[/name_m] choosing a few names from my own list…

Boys: [name_m]Alexander[/name_m], [name_m]Benjamin[/name_m], [name_m]Charles[/name_m], [name_m]Edward[/name_m], [name_m]George[/name_m], [name_m]Henry[/name_m], [name_u]James[/name_u], [name_m]Samuel[/name_m], [name_m]Thomas[/name_m], [name_m]William[/name_m].

Girls: [name_f]Alice[/name_f], [name_f]Charlotte[/name_f], [name_f]Daphne[/name_f], [name_f]Elizabeth[/name_f], [name_f]Grace[/name_f], [name_f]Jane[/name_f], [name_f]Katherine[/name_f], [name_f]Margaret[/name_f], [name_f]Rose[/name_f], [name_f]Susannah[/name_f].

Right…so that’s the thing, timeless and classic aren’t the same. A timeless name has been in use and varies in popularity. Obviously some of them are classics: [name_f]Mary[/name_f], [name_f]Elizabeth[/name_f], [name_u]James[/name_u], [name_m]William[/name_m], etc.
But the idea of the timeless list of names is that you don’t know the age of person with said name. And this isn’t purely an Anglo thing, either. For example, [name_m]Jose[/name_m] and [name_m]Juan[/name_m] and [name_m]Pablo[/name_m] were all on the list.
[name_u]Baby[/name_u] name wizard says both [name_u]Elliott[/name_u] and [name_u]Emmett[/name_u] are timeless, I suppose because it could be name of and old man or newborn. Clearly this varies by region, but any other thoughts on these particular names?

Nameberry says they are.

So is [name_u]August[/name_u], a huge favourite of mine which I originally fell in love with due to a Civil War-era abolitionist. But I doubt [name_u]August[/name_u] would make the classic list most people sketch out with [name_m]John[/name_m]/[name_m]William[/name_m]/[name_m]Henry[/name_m] and neither does [name_u]Emmett[/name_u] or [name_u]Elliott[/name_u].

On the other hand, there are names I love that I see in this thread that I still don’t think of as timeless, because I don’t know any [name_u]Baby[/name_u] Boomers by them, only the really-old or younger people. [name_f]Susannah[/name_f]'s classic (and gorgeous) but it’s not timeless, to me, because from 1940-1975 she was probably a [name_f]Susan[/name_f] or a [name_f]Suzanne[/name_f] or something and [name_f]Susannah[/name_f]'s not always in the Top Thousand.

[name_f]Elizabeth[/name_f]
[name_f]Grace[/name_f]
[name_f]Mary[/name_f]
[name_f]Jane[/name_f]
[name_f]Alice[/name_f]
[name_f]Katherine[/name_f]
[name_f]Anne[/name_f]
