Hugh le Despenser - husband of Isabel/Isabella de Beauchamp -called by history "The Elder" and his son Hugh "The Younger" have arguably been classed as two of the most evil nobles in British history as advisors to the despotic King Edward II. Both were executed for their crimes in late 1326 by Roger de Mortimer and his lover Queen Isabella. They are my ancestors as are Mortimer and Queen Isabella in different lines due to me fortunately being a descendant of Mayflower passenger Richard More, who has well-documented noble/royal ancestry.
The Despenser/Beauchamp marriage produced 4 children, 3 of them were in the More ancestry, Philip being one of those.
Per Douglas Richardson's Magna Carta Ancestry pages 275-76 and 612, Philip le Despenser (d.1313) was the 1st husband of Margaret Goushill (d.1349). The Philip married to Joan de Cobham was their son.
