VIII, 120 GERHARD
----------------------------
+ 1070 VIII 11
Count in Elsassgau, 1048 Duke of Upper Lorraine
oo Hedwig
+ n 1067 on I 28
Parisse, Noblesse Volume 2, p. 864, has compiled the documents relating to Duke Gerhard . Of course, Hedwig , the wife of Gerhard , must not, as Parisse does, be equated with a daughter of Count Albert I of Namur named Hedwig , as described in the Genealogia S. Arnulfi c. 4, SS XXV 383, since this message is incorrect information; see. on this Vanderkindere, Formation Volume 2, p. 454, and Brandenburg IX, 73-74. Poull, Lorraine Heft 1, p. 8, suspects that Gerhard's wife was of Lorraine origin.
Anyone know anything about the given source?
