King Richard I the Plantagenet, King of England did marry Berengeria of Navarre (as he second wife) the 12 of May 1992 in the St. George Chapel of Limasol, Cyprus.
However, that has nothing to do with Coultas simply because Coultas was not there. It is highly questionable if he did exist those days.
For the name to exist there must be a village or city of the same age with that name in Great Britain, There is None. I have ALL crusaders in my data base and the name Coultas is not there.
