William Beaumont, 2nd Viscount Beaumont

Sir William led an uneventful life until the feud between the houses of York and Lancaster broke into open bloodshed.

While he always claimed in life "...to let each man place his feet in the soil as the good lord intended..."(Bale, Robert (1461).

Beaumont obtained a general pardon two days before Christmas, but all his lands were declared forfeit and granted to Lord Hastings.

Between 1471 and 1474, he was continually at war, holding (amongst other bastions), St Michael's Mount along with John de Vere, 13th Earl of Oxford, for the Lancastrians in 1473.

Released by Sir James Blount in 1484, he landed at Milford Haven with Henry Tudor and fought against Richard III at the Battle of Bosworth Field on 22 August 1485.

Beaumont married firstly on 6 August 1462, Joan daughter of Humphrey Stafford, 1st Duke of Buckingham.

Upon the death of Sir William, the Viscountcy of Beaumont became extinct in both England and France and due to discord and fighting between his great-nephews, the title fell into abeyance.
