Onancock was the main trading town on the bay side of Virginias Eastern shore, one the few with deep water. Regular steamboat service to Baltimore & Hampton Roads. Before the railroad came to the shore majority of items sold would have come from Onancock. Supplied the Atlantic coast islands & fine Duck Hunting.
