"William de Malbedeng, Naissance ABT 1086
Wife Adelicia, Born 1110
Marié(e) abt 1127
"... William Malbank had a wife Adelisa. His most important fee was at Nantwich in Cheshire, and he is one of the few undertenants who are mentioned in the Domesday Book with a surname. At Wich we find that "when Earl Hugh received it, it was waste, except for 1 salt pan. William Malbank holds the same [Nant]Wich of the earl with all the customs belonging to it, and the whole of that hundred, which is valued at 40s., of which sum 30s. is charged upon the land of William himself." The salt panned at Nantwich brought in a substantial income since it was a necessity to preserve meat, and the monies that it sold for were shared both with the earl and the king. ...
William was dead by 1130 and was succeeded by his son Hugh Malbank. ..."
