From Wikipedia - Guînes

In 928 , when the Danes invaded and seized the place, it was probably a defenceless village. A fenced mound and a double ditch would soon have been created by the Danes. This is the origin of the castle of Guînes. Arnulf I , Count of Flanders , realizing a counter-attack would be costly, arranged the marriage of his daughter Elstrude, to Sigfrid, the Danish leader, bestowing upon him the title of Count of Guînes but as vassal to him, the Count of Flanders. Under Sigfrid's successors, the county of Guînes acquired considerable importance.

Sigfred married Elftrude, daughter of Arnulf I Count of Flanders and Artois and Adele of Vermandois. (Elftrude was born about 912 in Flanders, Belgium.)
