I believe that all the Longworths in the world are related and can trace their family origins back to Manchester in England. I am undertaking the enormous task of trying to link together as many families as I can. I currently have over 6000 names in my data base dating back to 1118. Any one wishing to contribute can contact me on brianlongworth.au@gmail.com. I am more than happy to share any information that I have. I also have some information on Facebook at http://www.facebook.com/group.php?gid=15981139934
