The Medical Shop on Lot 30 along Main Street, as recorded on the insurance records of Dr. Corbin Griffin, a physician who studied at the University of Edinburgh in 1765, was a simple frame building valued at $100. When the doctor acquired the lot, there were four structures on it, the shop, a residence, and two small out buildings. 
He was a patriot during the Revolution and served as a surgeon in the Virginia line. During the British occupation Dr. Griffin was taken prisoner by the British, and on September 25, 1781, his good friend General Thomas Nelson demanded Lord Cornwallis the following: “I must request that your Lordship will inform me of the Reason of Dr. Griffin’s Confinement on Board of one of your Prison Ships.” The doctor was released after the siege and lived to serve York County for many years as Justice, a member of the York County Committee on Safety, and a member of the State Senate. His wife, Mary, daughter of Colonel Edmund Berkeley, had eighteen children.
In 1806, the medical shop was acquired by Lawrence Gibbons. It is likely the building was taken over when Dr. Griffin went into politics. Mr. Griffin died in 1813. The great fire of 1814 started next door in Mrs. Gibbons’ house.
The old brick chimney foundations for the shop were found during exploratory excavations in 1935, which agreed with Dr. Griffins’ insurance 1796 records. In 1936 the National Park Service reconstructed the building.
