I can't post the link or else the mods will flip out, but if you go to ESPN's site and check their boxing page you'll find a very cool HW Championship Lineage timeline. It goes all the way back to the 1880's with Sullivan - complete with photos and even videos of most of the fighters.
Go to the boxing page and about half way down on the right side you'll see a link to the gallery. A VERY cool feature that all HW boxing fans should check out. For you newbies and youngsters on this board, it'd be a good reference to catch up on some history.
