William Bourchier, 9th Baron FitzWarin
William Bourchier jure uxoris 9th Baron FitzWarin, was an English nobleman. He was summoned to Parliament in 1448 as Baron FitzWarin in right of his wife Thomasine Hankford.
He was the second son of William Bourchier, 1st Count of Eu by his wife Anne of Gloucester, Countess of Stafford. His elder brother was Henry Bourchier, 1st Earl of Essex.
Bourchier married twice, firstly to Thomasine Hankford, one of the three daughters and co-heiresses of Sir Richard Hankford. Thomasine's mother was Elizabeth FitzWarin, 8th Baroness FitzWarin, sister and heiress of Fulk FitzWarin, 7th Baron FitzWarin, feudal baron of Bampton, in Devon. Their children included son and heir Fulk Bourchier, 10th Baron FitzWarin and Blanche Bourchier, who married Philip Beaumont, of Shirwell, Devon. Her stone effigy survives in Shirwell Church.
William's second marriage was in 1448 to Catherine de Affeton, daughter and heiress of John de Affeton of Affeton, Devon, and widow of Hugh Stucley of Affeton, Sheriff of Devon.
Both William Bourchier and his wife Thomasine were buried in Bampton Church. Dugdale quoted the will of his son Fulk Bourchier who bequeathed his body to be buried in the chapel of the Blessed Virgin at Bampton, near the grave of his mother, Lady Thomasine, and he willed that marble stones with inscriptions should be placed on his own grave and that of his father, Lord William, and his mother, Lady Thomasine. William and Thomasine's bodies were later interred under the altar flooring.
