changing the user name folder of administrator

I got married and changed my last name. I have a personal use macbook pro and I am the only account/administrator for my laptop. I have read many instructions involving creating a new administrator account and deletign the old one, but I wanted to know if there was any other way to change the name on the User directory folder. I changed my long and short name, and every other name on my accounts last year, but I have been unable to change the name on the directory. I have tried the chown -R /Users/old name /Users/new name in Terminal, but nothing happens after I enter my password. Can someone help? Thank you.
