What is "dodon"

Dodon, (aka "Doden") is a farm and former tobacco plantation in Maryland, located near the South River about south west of Annapolis. Purchased in around 1744 by the planter and politician Dr George H. Steuart, it remains the home of Steuart's descendants to this day. Steuart grew wealthy during the colonial era thanks to proprietarial patronage, but his family's prosperity and status would be much reduced by the American Revolution and later by the American Civil War.
