Also, a thing to note. Out of the 14 Monsters featured in the picture only 12 made it onto the actual the Monster Genealogy Chart. The two isolated at the top did not.

PS. The picture on the top right is of the great man himself John Bolton while working on the Monster Genealogy Chart (photo was sent to me by Liliana Bolton, wife & business manager of John), and the screenshot below is the actual chart that featured in the classic 1980 Amicus-style film starring Vincent Price & John Carradine.
