Fulk Bourchier was the eldest son and heir of William Bourchier, 9th Baron FitzWarin (1407–1470) by his wife Thomasine Hankford, a daughter and coheiress of Sir Richard Hankford (c. 1397 – 1431) of Annery, Devon, feudal baron of Bampton.

After the death of Fulk Bourchier, Elizabeth Dynham remarried twice, firstly to Sir John Sapcotes (died 1501) of Elton, Huntingdonshire; a stained glass heraldic escutcheon survives in Bampton church showing the arms of Sapcotes impaling Dinham.

After the death of Sapcotes, Elizabeth Dynham remarried secondly to Sir Thomas Brandon (died 27 January 1510) of Duddington, Northamptonshire.

[6] There was no issue of Elizabeth Dynham's marriage to Thomas Brandon, and according to Gunn, after his death she took a vow of celibacy before Bishop Fisher on 21 April 1510.

In his will, dated 1 April 1475 and proved 10 November 1480, he requested burial in the chapel of the Blessed Virgin at Bampton, Devon, next to the tomb of his mother, the Lady Thomasine.
