Gypsies/Israel

I'd be interested to hear from anyone who has any ideas about links between the Gypsies/Romanies and the ten Northern tribes of Israel who disappeared off the map centuries ago. I need some concrete evidence (documents? archaeology?) to back up some of the traditions that have been handed down.
Click 'COMMENTS' just below this if you have any information or to see what others have said before you.
Thankyou.

PS. Some interesting websites are out there including this one a friend put me onto: http://www.wallenbergcentre.net/gypsies.php
