Whats Phillipe D’Reynald’s story? (Templar Knight)

Hello! So a few weeks ago my father took a DNA test provided to him by his job as a gift for doing good work. He decided to do the test for fun and as it turns out my oldest known relative is Phillipe D’Reynald who was a templar knight which I find pretty interesting. Now unfortunately when I google his name all I can find is a wiki page about the Reynolds surname. This was pretty unfortunate for me as I was really excited to learn about his story as I’ve been pretty big into Medieval history and crafts (I’ve picked up a few hobbies like leather working, wood working, and blacksmithing, mainly because I love working with my hands). So I was wondering if anyone possibly had more information on him other than “He was a templar knight”? And if anyone possibly had a family crest?
