August 18 in history:
August 18th is the birthday of explorer Meriwether Lewis (1774), who traveled for more than two years with William Clark through the Louisiana Purchase territory and along the Pacific Coast.
It’s also the birthday of Virginia Dare (1587), the first child born at an English settlement in North America, the Roanoke Colony in present-day North Carolina. Virginia was the granddaughter of the settlement’s governor, John White, who returned to England for supplies shortly after her birth. White did not get back to Roanoke until Virginia’s third birthday in 1590, and found the colony deserted, with few clues about what happened to the settlers.
