Just Christian martyrs I'm assuming? Try this list (lots of obscure people I know, but I hope it helps)
Mr. No: it may not meet your definition, but an angry gun slinging mob shot Joseph Smith to death because he had a creepy religion. It meets mine, I guess. (I'm not a Mormon)
Where in the world did you come up with Joseph Smith? He's not a Martyr.
