For my personal associations - and with this spelling especially - it leans masculine but it wouldn't shock or disappoint me to see it on a girl.
It actually reached my long list for a girl when I was a teenager.
I feel that
Morgan is along the same vein - very gender neutral.
I'm not sure what you mean by country or suburb so I don't feel like I can answer it.
Riley on a boy is similar to
Jack in the fact that I see it as quite a soft name that means well and is likeable.
For a girl it's tougher, still "nice", but with more strength to it.
