Cornell Cousins -- Paul and Ezra

User Eric Ginsburg is trying to determine the connection between Paul Cornell, founder of Hyde Park, Chicago, and Ezra Cornell. He says they are frequently cited as cousins or even first cousins, but he can't find the relationship.

I don't believe we have a profile yet for Paul, but here is some information on him: http://en.wikipedia.org/wiki/Paul_Cornell_%28lawyer%29

Can anyone assist in figuring this out? Thank you!
