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"."
