The man who was Prince of Wales in 1399 came from what dynastic English house?
Dunstable Swan Jewel The Dunstable Swan Jewel is a gold and enamel brooch in the form of a swan made in England or France in about 1400 and now in the British Museum, where it is on display in Room 40. It was excavated in 1965 on the site of Dunstable Friary, and is presumed to have been intended as a livery badge given by an important figure to his supporters; the most likely candidate is probably the future Henry V of England, who was Prince of Wales from 1399.
John Wenlock, 1st Baron Wenlock John Wenlock, 1st Baron Wenlock KG (c.1400-04 - 1471) was an English diplomat, soldier, courtier and politician. He fought on the sides of both the Yorkists and the Lancastrians in the Wars of the Roses. He has been called "the prince of turncoats", although some historians suggest the label may not be fair. Others contend that even when Wenlock was not actually changing sides, he was engaged in "fence sitting "par excellence"."
