William de Aldeburgh, 1st Baron Aldeburgh

[1] After Ivo's death in the reign of Edward III, William received royal confirmation to hold a number of castles and manors, in Galloway and Broxmouth, which had been granted to his father by Edward Balliol.

[1] Aldeburgh married Elizabeth, daughter of John, 2nd Baron Lisle.

[3] This marriage brought Aldeburgh lands in Yorkshire, including the future site of Harewood Castle.

[2] Aldeburgh was granted a licence to crenellate at Harewood in 1366; he demolished the existing structures on the site and built the castle, which still exists (in a ruined state) today.

[2] Among his descendants was Lionel Duckett, Lord Mayor of London in 1572.
