Hundreds of pieces of broken wine bottles were found, including 11 wine bottle seals bearing the initials of George’s father, “AW”. During the 18th century only well-to-do planters imported wine bottles from England with their names or monograms stamped on the necks of the containers. Many wine-glass stems were also found, revealing the fine assortment of drinking glasses used by the Washingtons. Numerous windowpane fragments were unearthed.
