Oh, dude, you're mixing up your Dempseys! Patrick Dempsey, aka McDreamy from Grey's Anatomy, is not Jack Dempsey's grandson. Jack Dempsey was a famous boxer from the early 1900s. So, no family ties there, just some confusion in the name game.
The Jack Dempsey Fish came after the man Jack Dempsey. The fish was named after him because he was a boxer and the fish are known for fighting.
Jack Dempsey, Georges Carpentier, Gene Tunney, and Jack Sharkey.
Dempsey was a boxer, not a baseball player. May have done exhibition work at fairs and carnivals.

No, Patrick Dempsey and Jack Dempsey are not related. Patrick Dempsey is an American actor best known for his role in the TV series "Grey's Anatomy," while Jack Dempsey was an American professional boxer who held the world heavyweight title in the 1920s. The similarity in their last names is purely coincidental, as they come from different backgrounds and professions.
