Reading edition
Hoveden 1195, p. 430. Fordun, l. 8, c. 56, alludes to the occurrences at Clackmannan, but he confounds the princess Margaret with one of William’s illegitimate daughters of the same name who was married to Eustace de Vesci. Margaret afterwards married Hubert de Burgh, and Otho subsequently became emperor as Otho IV. His nephew Otho was the first duke of Brunswick and Luneburg.
