As the title says! I don’t have any in mind right now, except possibly [name_m]Alexander[/name_m] (though I’m not keen on it). It’s one of my favourite boy names and I love the nicknames [name_m]Ed[/name_m], [name_m]Ted[/name_m], [name_u]Eddie[/name_u], [name_u]Teddy[/name_u] and [name_u]Win[/name_u].
Berries, work your magic!
[name_m]Edwin[/name_m] seems perfectly versatile…so many different styles of names could fit!
a few random ideas that come to mind 
[name_m]Edwin[/name_m] [name_u]Sasha[/name_u]
[name_m]Edwin[/name_m] [name_f]Lilac[/name_f]
[name_m]Edwin[/name_m] [name_u]Atlas[/name_u]
[name_m]Edwin[/name_m] [name_u]Lex[/name_u]
[name_m]Edwin[/name_m] [name_u]Florence[/name_u]
[name_m]Edwin[/name_m] [name_u]Henry[/name_u]
[name_m]Edwin[/name_m] [name_m]Kip[/name_m]
[name_m]Edwin[/name_m] [name_m]Cosmo[/name_m]
[name_m]Edwin[/name_m] [name_u]Rhys[/name_u]
[name_m]Edwin[/name_m] Malachi/Edwin [name_m]Malachy[/name_m]
[name_m]Edwin[/name_m] [name_u]Jonah[/name_u]
[name_m]Edwin[/name_m] [name_u]Leo[/name_u]
[name_m]Edwin[/name_m] [name_u]Jasper[/name_u]
[name_m]Edwin[/name_m] [name_m]Nathaniel[/name_m]
[name_m]Edwin[/name_m] [name_m]Samuel[/name_m]
[name_m]Edwin[/name_m] [name_m]Ulysses[/name_m]
[name_m]Edwin[/name_m] [name_m]Caius[/name_m]
[name_m]Edwin[/name_m] [name_m]Felix[/name_m]
[name_m]Edwin[/name_m] [name_u]George[/name_u]
[name_m]Edwin[/name_m] [name_u]Beckett[/name_u]
[name_m]Edwin[/name_m] [name_u]Francis[/name_u]
[name_m]Edwin[/name_m] [name_m]Silas[/name_m]
[name_u]Love[/name_u] [name_m]Edwin[/name_m] [name_m]Silas[/name_m] to repeat and [name_m]Edwin[/name_m] fox?
I’m really fond of [name_m]Edwin[/name_m], he falls into two main categories for me: geeky and vintage. Both are 
but I might try to complement him with something more rugged and/or playful/modern in the middle. [name_m]Just[/name_m] writing rugged made me think of @Greyblue and her [name_m]Sholto[/name_m]. Sooo…
[name_m]Edwin[/name_m] [name_m]Sholto[/name_m]
[name_m]Edwin[/name_m] [name_u]Blake[/name_u]
[name_m]Edwin[/name_m] [name_m]Dashiell[/name_m]
[name_m]Edwin[/name_m] [name_u]Jesse[/name_u]
[name_m]Edwin[/name_m] [name_u]Jonah[/name_u]
[name_m]Edwin[/name_m] [name_m]Dacre[/name_m]
[name_m]Edwin[/name_m] [name_u]Jay[/name_u]
[name_m]Edwin[/name_m] [name_m]Shepherd[/name_m]
[name_m]Edwin[/name_m] [name_u]Jack[/name_u] (ok, that’s my favourite)
Searching for more syllables as something made you try him with 4 syllable Alexander…
[name_m]Edwin[/name_m] [name_u]Leander[/name_u]
[name_m]Edwin[/name_m] [name_m]Atticus[/name_m]
[name_m]Edwin[/name_m] [name_m]Arcturus[/name_m]
[name_m]Edwin[/name_m] [name_m]Anatole[/name_m]
[name_m]Edwin[/name_m] [name_u]Antares[/name_u]
[name_m]Edwin[/name_m] [name_m]Barnaby[/name_m]
I may be a teeny bit biased, but Edwin Sholto is wonderful 
Thank you for taking the time to respond 
@Evergreeninrain [name_m]Edwin[/name_m] [name_u]Florence[/name_u] is so beautiful! I also like [name_u]Atlas[/name_u], [name_u]Henry[/name_u] and [name_m]Cosmo[/name_m] with him. [name_f]Lilac[/name_f] on a boy is so cute 
@Greyblue [name_m]Edwin[/name_m] [name_m]Malachi[/name_m], [name_m]Edwin[/name_m] [name_u]Jasper[/name_u], [name_m]Edwin[/name_m] [name_m]Nathaniel[/name_m], [name_m]Edwin[/name_m] [name_u]George[/name_u] and [name_m]Edwin[/name_m] [name_u]Francis[/name_u] are dashing. Can’t believe I overlooked [name_u]Jasper[/name_u] when it was right in front of me
@Fabfitfun77 [name_m]Edwin[/name_m] [name_u]Fox[/name_u] is spunky, and I like the nature connection as well as the X-sound.
@EdgeOfTheMeadow I’m starting to like [name_m]Sholto[/name_m] these days, so [name_m]Edwin[/name_m] [name_m]Sholto[/name_m] was nice to see. [name_m]Edwin[/name_m] [name_m]Dashiell[/name_m] and [name_m]Edwin[/name_m] [name_u]Jack[/name_u] are adorable too. I’m so glad you had [name_u]Leander[/name_u], [name_m]Atticus[/name_m] and [name_m]Arcturus[/name_m] <3 in the list.
I love [name_m]Edwin[/name_m]! So underrated! [name_m]Edwin[/name_m] [name_m]Alexander[/name_m] is handsome.
