Baron Strange is a title which has been created four times in the Peerage of England. Two creations, one in 1295 and another in 1326, had only one holder each, upon whose deaths they became extinct. Two of the creations, that of 1299 and that of 1628, are extant. The surname Le Strange was Latinized as Extraneus. The arms of Le Strange of Knockin Castle in Shropshire were: Gules, two lions passant argent.

William Stanley, 6th Earl of Derby, KG was an English nobleman and politician. Stanley inherited a prominent social position that was both dangerous and unstable, as his mother was heir to Queen Elizabeth I under the Third Succession Act, a position inherited in 1596 by his deceased brother's oldest daughter, Anne, two years after William had inherited the Earldom from his brother. After a period of European travel in his youth, a long legal battle eventually consolidated his social position. Nevertheless, he was careful to remain circumspect in national politics, devoting himself to administration and cultural projects, including playwriting.
