I think I've met a few female Morgans in the past before but when I met a male Morgan last year, the name turned all boy for me. It's a nice, sturdy unisex name and though the name has been leaning more towards the girls side these days, I find it's evenly split. Definitely a cool name for a boy.
I think it's cute on a boy. I've never met a Morgan of any gender, but I think I'd prefer it on a boy.
I can't say because I live in England. In my local area I know more male Morgans than I do female, we're talking about an area where Ashley, Rowan and Alex are still boys names, i wouldn't hesitate to call my son Devon, Phoenix or Sydney around here. America is a different story though. I think you'd be better off asking some local friend on family to get an idea on whether your local community would find it weird or cool :)
I prefer Morgan on a boy and I wouldn't say that it's too common for a boy, either. It's actually been decreasing in popularity for boys (it was 587 in 2012 and 361 in 2003).
The only Morgan i've ever personally known was a male. I like it!
I vastly prefer it for boy, and I think it's one of the few names that can go either way without people freaking out over it. I think it's a very handsome name.
