I considered changing my name a while back, though for a completely different reason. I ended up not. I didn't want to alienate one whole side of my family, though they were part of the problem to begin with. I doubt you'll have that problem, but you may want to consider how the rest of the family feels.

When my mom's ancestors came through Ellis Island, their name was changed slightly. Not a lot, it was Italian, but it had some vowels axed. My dad's came down through French Canada, but the name was slightly altered anyway. Now I'm stuck with a French last name nobody can pronounce (except for a French-Canadian teacher I had once.)
