Return of prisoners, and where they are prisoned, 1600:

Marshalsey:

* Edward Bushell
* Captain Pluck
* Robert Gostrell
* Captain Whitlock

These four appear to have been imprisoned for their part in the Essex Rebellion (7 February 1601). The Earl of Essex was executed but many others were spared. Edward Bushell certainly was. He was a second cousin of Robert Catesby (one of the Gunpowder Plotters) but he went on to serve James I when he succeeded Elizabeth. Nothing is known about Captain Pluck; he may have been a "soldier of fortune" from the Irish branch of the Plucks who came across the Earl of Essex when he was in Ireland.
