Life with Boswell:
Boswell possibly was in William Douglas' company on October 6, 1762, when he visited Douglas' family at Kelhead. Boswell mentions a "Mr. Douglas, son to Sir John, an officer in the Greys, an amiable young fellow whom I hope to see in the circumstances which he deserves". However, Sir John did have two other surviving sons, at least one of whom was in the army. Also, it is doubtfulwhether Boswell would refer to a 32 year old as a young fellow.
JB also dined with Douglas and Captain Maxwell on December 20, 1762.
