  Research Notes:

The Annalista Saxo records the death in 1126 of "Heinricus dux Bawarie…filius Welphonis ducis…[et] Iudhitam". "Dux Gewelfo eiusque…uxor Iudita" donated property to Kloster Weingarten, with the consent of "filiorum suorum Gwelfonis et Heinrici", dated 12 Mar 1094. On the death of his father-in-law in 1106, he inherited extensive territories in Saxony around Lüneburg and in the Bardengau.

He was appointed to succeed his brother in 1120 as HEINRICH IX "der Schwarze" Duke of Bavaria. He initially supported the candidacy of his son-in-law Friedrich Duke of Swabia to succeed Emperor Heinrich V as King of Germany in 1125, but eventually supported the election of Lothar von Süpplingenberg, presumably on the understanding of his son's marriage to Lothar's only daughter, which took place in 1127. The enmity of the Staufen family which this created was to have far-reaching consequences in Germany for the rest of the century.

Duke Heinrich became a monk at Weingarten shortly before his death. The Historia Welforum records that Duke Heinrich became a monk shortly before he died "in castro Ravenspurch". The necrology of Lüneburg records the death "12 Dec" of "Henricus dux". The necrology of Weingarten records the death "Id Dec" of "Heinricus dux et m n c …pater Welfonis, hic sepultus". ¹
