Character inspiration from 19th century photographs

I have been trying to come up with drawings of the characters from Millicent Marbleroller. General Crackerhead and Nobbins have been the most difficult, although Mumbleskull has likewise been hard.

I decided that giving Teddy Roosevelt a mustache like Chester A. Arthur makes a pretty decent General.

Wagner - stern face, large face. I was wondering about Nobbins..

Schoepenhauer - if he looked a little happier and not as constipated I would say he is a good Mumbleskull. Needs coke-bottle glasses.

Some guy named Wattles Wallace - inventor of some sort. I was looking for thin faced men to help with the drawings for Admiral Crackerhead.
Pope Leon - another thinner faced man for the Admiral.
Thomas Huxley, an ardent supporter of the theory of evolution, who coined the term "agnostic" to refer to atheism because apparently at the time atheism was carrying a lot of socialist baggage. I thought his stern visage would make a good model for Nobbins.
