Career
Contrary to a few reports, there is no evidence of any relationship to William de la Pole of Hull, merchant and financier to Edward III. This was the Lordship of Mawddwy, consisting of Mawddwy and most of Mallwyd. John"s son Fulk predeceased his father without issue in about 1414. Accordingly, Mawddwy then passed to Fulk"s sister Elizabeth, who married Hugh Burgh.
Hugh Burgh"s son John (1414–1471) owned the lordship, but only left four daughters who were John"s coheiresses.
One of Sir John Burgh"s daughters, Elisabeth (Isabella) de Burgh (died 1522) married Sir John Lingen (died 1505), buried Aymestrey, Herefordshire and ancestor of the Sir Henry Lingen of Lingen, Sutton and Stoke Edith (died 1662),the family of Burton-Lingen of Longnor Hall and the 1st Baron Lingen (died 1905, buried Brompton cemetery, London).{Visitation of Shropshire in 1623, Robert Tresswell Somerset herald }
Another daughter Anchoretta de Burgh, married John Leighton of Streeton, later of Wattlesborough and Loton, Sheriff of Shropshire (d 1493) as can be seen on Stirnet.
