Count of Boulogne

Boulogne-sur-Mer became the centre of the County of Boulogne in the 9th century. The founder of the dynasty of the counts of Boulogne seems to have been Hernequin of Boulogne, the son of Ragnhart; Hernequin married Bertha of Ponthieu around 850. Later that century it was frequently raided by the Vikings. There is some uncertainly about the early counts; there are number of people called "count" but the first definite count does not appear until the 11th century.
