This summer, her crews of college students and volunteers are expanding their surveys. In May, the first diggers set out to find "His Lordship's Favor," a house built in the Zekiah in 1674 by Charles Calvert, the eldest son of Cecil, the second Lord Baltimore, and eventual heir to the title.
There, he told his father, "I resolve to live in the summertime." He believed it would be a "healthful" place, he said, and safer from political enemies than his mansion at Mattapany, where the Patuxent Naval Air Station is today.
Calvert told his father he intended to build a brick place, not one of the rot-prone, wooden, "earth-fast" structures common in the colony. In the end, however, he settled for just such a wooden structure set in the dirt "according to the fashion of the buildings of this country."
FOR THE RECORD - An article about an archaeological project in Charles County in Wednesday's editions included an error in a reference to the period. The artifacts discovered date from the late-17th and early-18th centuries.
The Baltimore Sun regrets the error.
And that - or rather its scant remains - is what King and her crews were looking for. Their only other clue to its construction was a 1705 map that included a tiny sketch of the property, showing what looks like a brick chimney, not the cheaper mud daub that most colonists chose.
After hacking their way through thick woods near the Charles County Landfill and digging hundreds of 2-foot-deep shovel tests, King's crew hit on a striking concentration of artifacts, including brick fragments.
But when the ceramics, pipe stems and a one-quarter slice of a Spanish coin from the 1730s were examined, she said, the site "didn't look like 1674." The oldest items she could find dated to the 1690s. If this really was Calvert's summer house, where were the signs of occupation from the 1670s?
"So, I go back into the records and realized that Charles Calvert built the house, and has every intention of living there, but the circumstances of one's life change," she said. Perhaps Governor Calvert just got too busy to actually move in.
There were clashes between Maryland and Virginia colonists (including John Washington, George's grandfather) and the Indians. The violence threatened everyone's safety. There was an uprising by Virginia frontiersmen against the government. And there was unspecified business in 1676 that took Calvert back to England for two years. By 1684, he had left Maryland for good and the summer house was sold.
So, "he built the house, but maybe he's just not there," King said. The artifacts they found could be the refuse of later tenants or owners who lived there into the early 1700s. On the other hand, if it's not Calvert's house, it's not at all clear from the archival record just who else's it might be.
