Either a redneck (guh, how I hate that word, but it's the best image I can convey) or a doctor who researches cancer. (The reason for the extreme difference in mental images is because I once played a guessing game with a classmate where I tried to guess his dad's name... and it was
Roy. And he's a doctor. End useless anecdote.)
I just don't see it as a name that fits you, KWIM? However, if it's to honor your uncle (especially one that you're so fond of), then I think that could trump all other perceptions.
