Rumney and Mercer apparently consulted with one another today about Patsy Custis’s case and decided on a new way of treating her epilepsy, because four days later Rumney recorded giving her mercurial pills, purging pills, and ingredients for a decoction (receipt from William Rumney, 18 Feb. 1769, ViHi: Custis Papers). Unfortunately, those medicines, like the others tried previously, would give Patsy no relief from her fits.

The youngest son of Thomas Addison (1679–1727) of Oxon Hill, Md., was Rev. Henry Addison (1717–1789), rector of St. John’s Parish, Prince George’s County, Md., from 1742 to 1775. At this time Addison, a friend of Jonathan Boucher, had placed his two sons in Boucher’s school in Caroline County, Va.; the Addison boys appearing here are probably those sons. Col. John Baynes (c.1726–1785), a local Maryland merchant with Whitehaven connections who worked out of his store at Piscataway, Prince George’s County, Md., had at least one son, Joseph Noble Baynes, who was about 18 years old in 1769 and, like the Addison boys, was probably a schoolmate of John Parke Custis (boucher [1] description begins Jonathan Bouchier, ed.
