Thomas Howard, 4th Duke of Norfolk
Thomas Howard, 4th Duke of Norfolk (March 10, 1536 — 1572) and 1st Earl of Southampton, was entrusted by Queen Elizabeth I of England with public office despite his family history and his prior support for the Catholic cause, although he claimed to be a protestant and had been taught as a child by John Foxe, the Protestant martyrologist, who remained a lifelong recipient of Howard's patronage.
The queen imprisoned Howard in 1569 for scheming to marry Mary, Queen of Scots. Following his release, he participated in the Ridolfi plot with King Philip II of Spain to put Mary on the English throne and restore Catholicism in England and was executed for treason. Some doubt the strength of the evidence for his participation in the Ridolfi plot.
Norfolk's lands and titles were forfeited, although much of the estate was restored to his sons. The title of Duke of Norfolk was eventually restored 4 generations later, by his great-great-grandson, Thomas Howard.
