In 1819, Territorial Governor Lewis Cass and his staff rode on horseback from Detroit to a rendezvous that would result in the Saginaw Treaty and stopped for lunch beneath a large oak tree near what is now the intersection of Main Street, Rochester Road, and Crooks Road. While resting there, Cass recounted the story of Prince Charles II after the Battle of Worcester, the final battle of the English Civil War. To escape capture by the Roundheads, who sought to eliminate the English monarchy, the prince was said to have hidden in an English oak tree in Boscobol Wood, England, where he remained undiscovered until allies brought him to safety. After nine years in exile, he became King Charles II, and the tree that saved his life became an English national monument known as the Royal Oak. Local history holds that as Cass lay on the ground looking up into the spreading branches of the oak sheltering his luncheon, he remarked, "This truly is a Royal Oak," giving the place its name.
