Some years ago there were a few discussions in this newsgroup about the maternity of Ingegerd Knudsatter if she was legitimate daughter of Canute IV and Adele de Flanders or if she was illegimate daughter of Canute IV. This particular question is important because Ingegerd is ancestress of many people in modern Scandinavia and if she was Adele's daughter then she would have descents from Charlemagne giving Charlemagne descents for many people in modern Scandinavia. The discussions said the doubts over her maternity emerged because she didn't went with Adele back to Flanders after her father's murder. However this point is very questionable because her sister Cecilia whose status as daughter of Adele doesn't seem to have being brought into question in the discussions also didn't went with Adele back to Flanders and besides in the political view a boy was certainly more important to take care of than two girls. Also in support for Ingegerd's status as daughter of Adele is the testimony of Saxo Grammaticus mentioned in http://fmg.ac/Projects/MedLands/DENMARK.htm#_Toc360005000. Saxo was writing about a century after the facts so I think we can consider his testimony about it as trustworthy and he certainly had acess to sources that don't exist anymore. Saxo says that after Canute IV's murder Adele run to Flanders with her baby son Charles whereas she left her twin daughters Ingegerd and Cecilia in Denmark and then they went to Sweden with their uncle Erik I. In conclusion I don't think there is any reason to doubt Ingegerd's motherhood and so Scandinavian members of the newgroup descendants of Ingegerd you can get rested. As usual comments on the matter are welcome.
