Because there are no guidebooks on how to create a tercentennial celebration, several members of the Manor Conservancy took matters into their own hands by forming the Manor 300 Committee with representatives from other nonprofit groups, churches, schools and historic societies.

The committee members began planning ways to commemorate the day in 1713 that Charles Calvert, third Lord Baltimore, deeded 10,000 acres in northern Baltimore and Harford counties to his wife, Margaret. Although Margaret never saw the land before her death, it was called My Lady's Manor.

So far, committee members have organized a tour through seven cemeteries in My Lady's Manor, a discussion of the Northern Central Railroad, a concert at Ladew Topiary Gardens and a half-marathon on the Torrey C. Brown trail.

An even bigger event is planned for Sept. 29 at 12:30 p.m. at the St. James Episcopal Church grounds in Monkton when the current incarnation of Lord Baltimore — Scott Watkins — will arrive on horseback to kick off the free, family-oriented afternoon.

"Our idea is to celebrate the people who were in My Lady's Manor throughout its history," said Scott Watkins, a member of the Society of Colonial Wars in the State of Maryland and an actor who plays Lord Baltimore.

Re-enactors include Native Americans who lived in the area and soldiers from the Revolutionary War and the War of 1812.

The Old Guard Fife and Drum Corps from Washington, D.C., will be there, dressed in Colonial uniforms with tricorn hats. State and local officials will be on hand, as well as a representative from the British Embassy.

A plaque donated by the Society of Colonial Wars in the State of Maryland will be unveiled. It will later be erected on the grounds of the church, which dates back to 1750.

Students from St. James Academy will sing "God Save the Queen," "Maryland, My Maryland" and "The Star Spangled Banner."

The Maryland State Archives will bring the original deed, or patent, dated Aug. 26, 1713, to be displayed in the St. James church hall.

Visitors are encouraged to bring chairs, blankets and picnic lunches and stay after the festivities to soak up some of My Lady's Manor's ambience.

"This will be the culmination of our efforts to recognize and celebrate the 300th and to promote an appreciation for the heritage of My Lady's Manor," said Gloria Cameron, of Monkton, who chaired the Manor 300 Committee. "It is going to be a delightful pageant."

Cameron was instrumental in getting several local artists to create commemorative items for the tercentennial.

She asked the husband and wife team of Jerry and Janet Beaumont, who own Beaumont Pottery in Jacksonville, to make stoneware mugs for the occasion.

"When we went to England in April, we took photos of mugs in museums so we could get ideas," Janet Beaumont said. They eventually based their mug and handle design on pewter mugs popular in the 1700s.

Jerry Beaumont, a potter for 50 years, made each mug. Janet inscribed each one with "My Lady's Manor, Deeded 1713. Lord Baltemore's Guift. Tercentennial 2013." (The unique spelling is said to have come from Lady Baltimore's will.)

The 16-ounce mugs are microwave and dishwasher safe. They are $37 and can be ordered at

White Hall artist Betsy Hermann was commissioned to create a limited edition print that shows the historic structures and natural features of My Lady's Manor and the surrounding area.

"Gloria wanted the print to depict the legacy of 300 years within My Lady's Manor's border," Hermann said. She identified rivers, main roads, houses, taverns and tracts of historic value. Some 64 structures are numbered and identified.

The 18 by 24-inch print is $65 and can be ordered at
