First thoughts on whether these are boys or girls?

[CocoPorridge]

If you heard the following names but didn't see the child/know any other details, would you assume they were boys or girls? You haven't seen the names written down so spellings make no difference.

Frankie
Ronnie
Charlie
Sidney/Sydney
Morgan
Riley
Jordan
Ashley
Aubrey
Addison
Emerson
Mackenzie
Phoenix
Brodie
Brogan

Girls:
Frankie
Morgan
Ashley
Aubrey
Addison
Emerson
Mackenzie

Boys:
Ronnie
Charlie
Sidney/Sydney
Riley
Jordan
Phoenix
Brodie
Brogan

Influenced by the fact that I grew up and live in the US, they could all be either except Emerson, Brodie and Brogan which are definitely boys, but my first guess would be:

Frankie boy
Ronnie boy
Charlie boy
Sidney/Sydney girl
Morgan girl
Riley 50/50

Jordan If a child, girl
Ashley girl
Aubrey girl
Addison boy
Emerson boy
Mackenzie girl
Phoenix 50/50
Brodie boy
Brogan boy

Why OP?
