I have located the profiles for the stars of ''The Wizard of Oz'' which are on the following open-space profile (http://www.wikitree.com/wiki/Space:The_Wizard_of_Oz_Film).
I had previously worked on connecting Bert Lahr (The cowardly lion) without success. Tonight, though, I found a connection for Margaret Hamilton (The Wicked Witch of the West).
Margaret's Great Grandfather's (Justus Hamilton) sister Juliana was married to Edmund Rathbun/Rathbone Jr.. Edmund's grandfather Jonathan is 18 degrees from AJ!
I think she should be 25 steps, but will have to wait for the reload.
Congratulations, Ron! Looks like you were so excited to post this that you forgot to sign in.
