Grand Duke Bernard Docken is remembered for his marriage to a Forestwoman, resulting in a united Isle of Brickdocton upon his becoming the Seventh Lord Brickdocton, an authority both the Forestmen and the Avalonian colonists agreed to submit to. During Bernard's rule, the Guild of Avalonia came to power, and under Bernard's leadership, the colony recognized the authority of both Albion and Cedrica .

He was presumably the son of Barnaby Docken and the father of Bartholomew Docken .
