My first two novels feature members of the Despenser family, which suffered from several revolutions of Fortune's Wheel before the male line died out in the early fifteenth century. Here is some more information
about the various members of this fascinating, often ill-fated family (keep checking for updates):
The Other Hugh le Despenser (d. 1349)
Three Little Nuns (Joan, Eleanor, and Margaret le Despenser)
Divorce, Medieval Style (Isabel le Despenser)
