William de Redvers, 5th Earl of Devon

[3] He was the son of Baldwin de Redvers, 1st Earl of Devon by his wife Adelize Ballon.

In 1194, De Redvers took part in the second coronation of King Richard the Lionheart (1189-1199), when the Canopy was supported by four Earls.

He was a firm supporter of Richard's younger brother and heir King John (1199-1216), but after John's death, he permitted Falkes de Breauté, one of his mercenary captains, to seize De Redvers' widowed daughter-in-law, force a marriage, and take her dowry.

These events are featured in Alfred Duggan's novel, Leopards and Lilies (1954).

He married Mabel de Beaumont, a daughter of Robert de Beaumont, Count of Meulan by his wife Maud FitzRoy, a daughter and co-heiress of Reginald de Dunstanville, 1st Earl of Cornwall by his wife Beatrice FitzRichard.
