Nickname-Names

It's amazing how many ways a new name can come about. While diminutives becoming names in their own right is something we're all familiar with (Kate, Jack, Mia, Liam), I was surprised to find out how many names were originally descriptive nicknames. As you can imagine, most were originally surnames, but a few were first given in honor of a single famous individual.
I'm leaving out nicknames derived from places/nationalities (done that already), those derived from animals (way too many), and those derived from hair/eye/skin color (again, too many, and they've mostly been covered already, too).
It's also worth noting that English often has a tendency towards sarcastic nicknames--"Tiny" for a big fellow, "Happy" for a rather dour person, "Einstein" for a slow thinker, etc.
