Robert the Bruce, King of Scotland had a brother Edward. Edward had an illegitimate son Thomas from whom the Bruce family of today is descended. Two excellent and reliable websites on the Bruce lineage are brucefamily.com/lineage and electricscotland. Your James is in brucefamily.com but you must read carefully as the lineages are broken into baronies like Airth, Clackmanon, Kinniard, etc I hope this helps. C Evans
