Life with Boswell:
It is unclear when Boswell first met Elizabeth Bosville. He was introduced to some of her family, at least her brother William, in 1763. In a letter to William Temple dated May 17, 1766 he wrote that "Miss Bosville is a charming young lady. I got her to speak a good deal before I left London and found her extremely sensible. She never dances. That I should have insisited, for no man shall ever pull about my wife. She loves reading and walking, and does not tire of six months in the country. [...] I dined three or four times a week at her father's while I stayed in London." 1
He seriously considered marrying her for some time before, eventually, she married one of his acquaintances, Alexander Macdonald of Sleat.
