De Lusignan-125 and Lusignan-6 appear to represent the same person because: De Lusignan-125 appears to be simply a mistake, attached to the brother of the real husband. For example even the bio text we have for Henry mentions Humphrey! (So apart from merging we should disconnect from Henry it seems. Unless there is a special story here.) Medlands and other easy to check sources seem to indicate nothing known of what happened to Henry.
