Wikipedia:Articles for deletion/Robert de Bruges
Ref 1 indicates that he did exist and was castellan of Bruges in 1054.  Everything else is pure specualtion, which in WP, we call .  In this case the OR is not by the WP editors, but the compiler of an external website (Ref2).  The choices are (1) Delete (2) reduce to the statement about his existence and "some researchers have suggested him as a remote ancestor of the Robert Bruce".  At this remote period biographic (and genealogical) details are often sketchy (or non-existent).  Unless there is something substantial to say about him, I would suggest he is NN and the article should be deleted
