Hans came to America on the good ship Loyal Judith on 25 Sept 1732 at the port of philadelphia. On page 80 of "The Pennsylvania German pioneers" is Georg's signature. I am a descendant of georg and my aunt, Berniece Throne moxley wrote a book in 1975 called "Hans Georg Throne A Geneology" I belong to the Abraham line of Throne's which moved to Ohio and then Michigan. I don't believe the book is in print any more but some libraries do have a copy. Hope this helps.
