The only people with the name spelled
Remi (and one Remii) in Australia are all female. I'd assume
Remy was a boy but I wouldn't be sure and I have mostly only seen
Remy on a boy in US and UK BAs.
I agree
Remiel has a good meaning but for some reason I'm feeling like it sounds like a cosmetic brand in Australia but I haven't been home in awhile so I'm blanking- and could be wrong.
I'd go
Remy for a boy. He might still have the, "I'm a boy called
Remy" thing but not as often as
Remi.
