I wanted to put down the story that this 90 year old man told Lynda is the probable beginnings of these Ward families. He said that these men were Syrian Jews. They moved into the border area between Scotland and England with the Roman conquest. They lived there for many generations and because they were Jews they were given the less glamorous jobs of being the guards. These men were left to protect the Roman interests when the Romans pulled out. When surnames were put into place (After 1066, the Norman barons introduced surnames into England, and the practice gradually spread.) these men were given or took the name of Ward or Warden. These families lived in the borders area of Great Britain for many generations.
I wanted to write this down so I don't loose the thought.
