Name website that finds related names?

CD+AL

My grandmother's name was Gladys, which I'd never use, but when I ran across Claudia in a name book I found out it is actually derived from Gladys.  DH nixed Claudia (it's meaning beyond it's relationship with Gladys isn't that great anyway), but it made me think that there might be other names we would consider that are related to Gladys. 

Anyone know of a website that allows you to enter a name and find other names that are derivatives for it?  I googled but didn't come up with much with the search terms I was using.
