From 1777 to 1783 James Boswell was a columnist for the London Magazine, writing a total of seventy essays under the pseudonym the Hypochondriack.
Nathaniel Gould - Colonel
Nathaniel GouldDied 1786
Sometime Lt. Colonel. Married (1752) to Frances Mary Buckworth (d. 1759). Married (1759) to Elizabeth Cochrane, Boswell's mother's cousin. He had two children from his first marriage, Fanny (b. ca. 1755) and Buckley (possibly b. 1752 in Weston, Somerset).
According to Boswell (LJ031262), Lt-Col Gould participated in the Affair of St. Cast.1
Boswell first met Nathaniel Gould on December 03, 1762. During the following months he often dined with the Goulds, and enjoyed their company. Boswell especially seems to have taken a liking to the Colonel. (In LJ080163 Boswell describes the Colonel's charming indolence)
Nathaniel Gould's daughter, Fanny, is probably the Fanny Gould who married Lt-Gen Charles Horneck (Link) in Bath in 1790, and died in 1832 (Link). If this is the case, she is also the Fanny Horneck who married the poet Rev. Thomas Sedgwick Whalley (1746-1828) in 1812 (Link), and who was of extravagant habits, and came to him in debt to the extent of some thousands, for which he found himself responsible.2
