Preview: Patchen-Cushings descended from William Bradford?

I'm still trying to get a handle on this.  I've found genealogies that link the Cushings back through William Bradford, Mayflower passenger and first Governor of Plymouth Colony.  If the data is accurate, this would make Bradford my 8th great grandfather (11 generations back).  Because of existing research on Bradford's descendants, this would make us distant cousins to the likes of Julia Child, William Renquist, George Eastman, Clint Eastwood, Harold Edgerton, Benjamin Spock, George Bush, Hugh Hefner, and others.  It may be awhile before I can be reasonably sure of the link.
