Yep..not a well known fact that Bob Marley was half white..like you said..his father was white and British.

They originally thought the melanoma on his toe was an injury from playing soccer but in fact it was cancer which spread throughout his body.

Speaking not-well-known facts, (totally un-related to Bob Marley)

Robert Deniro is actually more irish than italian. His mother was of irish ancestry and his father was half italian and half irish..he ended up with an italian last name but he's %75 irish. Weird.
