There are maps of each region, and a map of the world showing, the oldest business in each country that has continuously operated and when it started.

When the real estate bubble popped and values nosedived they couldn't handle the debt and went belly up in 2006 becoming a subsidiary of Takamatsu Corp.
One of the slaves at Shirley Plantation, Siah Hulett, escaped and served on the USS Monitor.
