Egon, your wikipedia reference is to Leopold I , the Illustrious/Serene (* around 940; † 10 July 994 in Würzburg ), also called Luitpold , from the Babenberg dynasty , was Margrave of Austria from 976 to 994. This is another wikipedia page for him: https://en.wikipedia.org/wiki/Leopold_I,_Margrave_of_Austria

• Leopold, I "the Illustrious", Margrave of Austria

and you're right - he does need cleaning up.
