I can't find the right profile, someone knows? He's also known as 'du Plaisis' at dutch wikipedia.
Reference: https://en.wikipedia.org/wiki/Phillipe_de_Plessis
13th Grand Master of the Knights Templar. He helped uphold the treaty between Saladin and Richard I. Is he related to the 'Dr. Jean Prieur du Plessis' family ?
Found ! Although it's a stand-alone profile ' named 'de Plessis' of Pam Wilson PM.
Phillipe de Plessis, 13th Templar Grand Master
hello Private User,
Phillipe de Plessis, 13th Templar Grand Master is a standalone profile because despite any theories that may exist there is simple no evidence of any family connections for this man. Obviously he would at least have had a mother and father if no siblings, wife or children but there are simply no records of such from nearly 1000 years ago.
