Removing Name from Username?

[newyorkcity]

I just got my mba 11" and my username is my real name instead of the name of my home folder. When I goto System Preferences > Users I see I'm logged in as the admin and it also displays my icloud email address which I wouldn't want to be displayed.

Is there any way around this?

OS X Automatically puts in my name as well, however, my Username also works. It should be the same with yours.
