I just want to say, I don't know if I'd say
Avery is only used for girls in Canada. I'm from the Northeastern US, so I can't imagine it would be that different here.
Avery is a bit more common for girls at the moment, but it is not yet well established as a girls name and is still definitely unisex. I for one consider
Avery a lot more masculine than feminine, and I believe I've seen it in both male and female
BAs. I'm sure it has a lot to do with your personal experiences though. I hear about a lot more female Addisons, but I also knew a twenty-something male
Addison and it totally worked.
