Harvey since it's really the only boy name on the list. 

I don't care for any of them..to be honest.

Harvey I guess, the other ones are just way too girly for me. 

None honestly. 

None.  
Harvey is bleh.  Ashley and Cassidy are far too girly. 

I love Harvey!

Ashley is definitely not a girls name here, must be a location thing? I like it :)

Cassidy is not for me at all.

I love Harvey but that's mostly due to Sabrina as a kid haha

Ashley is the masculine spelling of the name (Ashleigh is typically the girl variant), it was traditionally a surname which turned into a boys name :D 

I only added Cassidy as its my partners pick for a boy is we ever had another.

Ashley is the traditional masculine spelling of the name where as Cassidy is unisex.
My partner love Cassidy but he still says even he thinks it sounds too redneck - granted we are Australian so that's not really a factor, I think he is just overthinking what his family in America would think haha

I love Harvey! I like Ashley for a boy but wouldn't use it becaus here in the US it is mostly used as a girls name now.  I don't care for Cassidy.

None personally

None, but I voted for Harvey because my son has a Harvey in his class. 

I would consider Cassius or Casey over Cassidy. 

Theyre all kind of "bleh" for me... I did choose harvey though. Harvey makes me think of an old biker dude. Ive heard Ashley as a boy name, but i think its god-awful. And cassidy isnt a boys name at all.

IMO, none.

I like Harvey the best. Cassidy reminds me of a girl :( my sons name is Cassius though. Pronounced Cash-US. 

If I absolutely had to choose one I would choose Ashley, but it's still bleh.
