William Spurrier died in January 1801. John Spurrier died in 1810. The Maryland Chancery Court ordered the tavern property and other lands to be sold to settle John Spurrier's estate.
Rosalie Stier Calvert bought the tavern and land with her father's money at public auction in June 1811 for $20,000. The Stiers were a Belgian aristocratic family that came to the United States as refugees from the European wars of the 1790s. For a time, the Stiers lived at the
William Paca House in Annapolis before building
Riversdale House in Prince George's County. Rosalie Stier married
George Calvert in 1799. Circumstances forced her Stier relations to return to Belgium and Rosalie Calvert's father left Riversdale to her along with funds to invest for her children. The Spurrier's tavern property was earmarked for Rosalie's oldest child, Caroline. The Spurrier family had leased the property to Henry McCoy on a seven-year lease before putting the property up for auction. As the lease holder, McCoy had
naming rights. The tavern was known as McCoy's until 1818. In 1814, McCoy became postmaster of McCoy's post office, the first post office along the north–south road in what is now Howard County. The post office was closed in 1815 and reopened in the tavern in 1819 as Waterloo, remaining open until 1836. George Calvert became the president of the new Baltimore – Washington Turnpike Company, charted in 1812. In constructing the new turnpike, the road was rerouted further west, just south of the tavern so as not to distance it from passing traffic. Rosalie Calvert also bought of land along the north–south road, in part to prevent anyone from building a tavern in competition with hers. Calvert and her family were pro-English and considered the British to be the saviors of their home country, Belgium. The family estates were near the site of the
Battle of Waterloo. Calvert named the tavern Waterloo. She named another property she bought with her father's money Waterloo as well. Rosalie Calvert died in 1821. An 1827

Decline and later ownership The B&O Railroad was constructing the
Thomas Viaduct across the
Patapsco River near Elk Ridge Landing as part of the railroad's route to Washington City. By 1834, the viaduct was nearing completion, and the railroad was laying the railroad tracks to Washington. One operation was just east of the Waterloo Tavern where crews were cutting a pass through a hill, called Jessup's Cut. In late 1834, the railroad crews rioted and the violence spread west to the tavern. Several outbuildings were damaged. The local Maryland militia was called out to restore order. By the late spring of 1835, construction was complete, the tracks had all been laid and the B&O company started running trains to Washington. The B&O Washington line spelled doom for the stage companies operating along the Baltimore-Washington Turnpike. Conveniently, there was a fire at the tavern during July 1835. Just as conveniently, contemporary newspaper accounts of the fire related that a stage coach had stopped during the fire and the passengers were available to help evacuate Merrill's property from the tavern. The fire enabled Merrill to get out of his lease. The tavern, though not destroyed, was no longer a viable business enterprise. In January 1836, George Calvert dumped the Waterloo property on his daughter. The property was transferred to Caroline Calvert Morris with her brother
George Henry Calvert designated as trustee, thus leaving Caroline's husband with no control over the property. Caroline Calvert had married Thomas W. Morris in 1823. In the late 1830s, the family lived at the Waterloo property during warmer weather while Thomas Morris was effecting repairs to make the old tavern building suitable as a year-round residence. The Morris family was living full-time at Waterloo by 1839. By the early 1840s, Thomas Morris had changed the name of the property to Glenthorne. The name did not stick and the property was known as Waterloo in the land records after Thomas Morris died. Caroline died in 1842. Her father had died in 1838 and left his entire estate to his two sons. Thomas Morris made efforts to determine which of the Calvert properties were actually a part of George Calvert's estate and which belonged to Rosalie's father's (Henri Stier's) estate, to try determine if his wife, Caroline, had an interest in any other properties that were not part of her father's estate. Ultimately, through a lawsuit, in 1846, Thomas Morris was able to obtain an additional $11,000+ for the devalued state of the tavern property but little else from George Calvert's estate. After their uncle George H. Calvert transferred control of the Waterloo properties to the four surviving children of Caroline and Thomas Morris, they sold the properties in three transactions in 1852 and 1853. By 1852, the holdings were in four parcels, Brown's Purchase, Second Discovery, the Anvil, and a second segment of Brown's Purchase. All but the Anvil, including Waterloo Farm, were sold to David P. Hayes, who continued to own some of the property as late as 1891. ==1900s==
