Henry Pole the Younger rides again?
Yes, that Henry Pole. A contact asked us recently whether his mother (nee’ Jane Neville) had been arrested in November 1538 and executed with her husband (Henry Lord Montagu) and others that December or January. Online sources are confused about this. However, we do know that she was the daughter of George Baron Bergavenny and was born at about the same time as Montagu (1492), because Henry the Younger was probably under sixteen in 1542 and was not openly executed for this reason.
Pierce’s Margaret of Salisbury biography confirms that Jane’s death preceded the plot and possably pressaged Montagu’s participation in it, although her brother Sir Edward Neville was among those arrested and executed. The CP, citing the Letters and Papers of Henry VIII, confirms Jane’s death by 26 October 1538 and Sir Edward’s subsequent execution.
The ODNB states that Henry the Younger, together with his exiled and yet to be ordained uncle Reginald, was being considered by the plotters as a husband for Princess Mary. This may explain why he too was arrested and disappeared, yet his married elder sisters (Catherine and Winifred) were not.
Incidentally, Jane Neville was also descended from Constance of York.
