Sir James Fagan - Was James Fagan a son of Christopher and Mary Fagan?

I am a direct descendant of Christopher and Mary through their first son Patrick, who had 22 children. All the sons are documented in Burke's earliest volumes and have been researched and further documentation done by dedicated descendants around the world. There is no record or family lore that validates the claim that James Fagan was a son of Christopher and Mary, or a brother of Patrick. In addition, there is no record of any Fagan being knighted. I have written a more thorough response to the claim of Sir James Fagan that is posted on Ancestry.com as a story associated with both Christopher Fagan and his son Patrick. I invite you and anyone else who is interested in knowing the facts. If you have any actual source material that proves your claim please let me know and I will gladly update our records.
