Howe how do i change the name of my home folder?

I was completing a form and i noticed that it was commenting in a name that i have never used on this computer. did a little digging and discovered that this name is the name of my "Home" folder. The name is my wife's late husband's name!!!! LoL I have absolutely no idea how that possibly could have become the name of my computer since I have never used that name!!!! Well for some reason I can find absolutely no way to change it. Geez folks, did I somehow stumble in the Microsoft world? I thought Macs were easy! LoL. The name of my computer is correct. Now how do I change the name of my "home" folder, whatever the f**** that is????

Thanks!
