Pros: I like the "she-bear" meaning and association. Ursula K. Le Guin is an awesome namesake.
Cons: The sound is unattractive especially the "ur" part. Ursula the seawitch is popular and is the first thing that pops up with a Google search; Ursula is a well crafted villian, but I wouldn't want to be tied to her in anyone's mind.
The cons outweigh the pros for me. I rate it 4/10.
