Some of the material concerning early English Jordans comes from a reported Jordan who fought as a knight in the Crusades (about 1200 A.D.). If he was a knight, then he probably was a Norman. He took his name from the Jordan River. Most of the Jordan names I have seen before 1600 were in England, but there were some in other European countries. They probably all took their name from the river - for religious or other reasons. So, many Jordan lines are not related. We can be thankful from a genealogical point of view we are not Johnson, Brown, Jones, or Smith. Bob
