Greater Upper Marlboro in Prince George's County, Maryland — The American Northeast (Mid-Atlantic)
Billingsley's Point
Colonel Thomas Hollyday bought the property from Billingsley's heirs in 1687. Hollyday. an influential man in political and business circles at Mount Calvert, built a house on the property. The building is long gone but archaeologists discovered traces of a wood framed building near the existing house. Research suggests this was the original Hollyday dwelling built in the 1660s. They believe it was Hollyday's house.
The large brick home at Billingsley was constructed in the 1740s, most likely by Dr. James Weems, who purchased it from Hollyday's son in 1740. The Weems family occupied Billingsley for the next 100 years.
An Indigenous Legacy
At Billingsley's Point, just across Western Branch from Mount Calvert, archaeologists have recovered thousands of Indigenous artifacts. These discoveries suggest that Native people first arrived in the region at least 13,000 years ago and continued to occupy the land until the arrival of Europeans in the 1600s. Recent excavations revealed a major settlement at Billingsley between about 4000 and 2000 BP.
The Patuxent and Mataponi tribes lived in villages called "Wighkawamecq" and "Coppahan" when Major John Billingsley was granted the land by Lord Baltimore in 1662. Archaeologists discovered that the Native people continued to reside at Billingsley until the late 1600s when they were driven out by the Europeans.
