Is Mark David Chapman related to Dog the Bounty Hunter?

I watched a documentry on Mark David Chapman and Dwayne The Dog Chapman was in the documentry it was stated that he was the uncle of Dwayne Chapman (The Dog) however i find this diconserting because Dog was born and raised in Denver and Mark David Chapman was born and raised in Hawai, its quite possible that they are related as stated in the documenty, with that being said if in fact they are related it just proves that the Apple indeed does not fall from the tree, David Chapman (criminal) Dog The Bounty Hunter (Somewhat reformed Criminal)
