Marquerite KinlochBorn 1742
Daughter of James Kinloch (1705-1778) and Anne Marguerite Wild. Married (1774) to John Christopher William de Rham (1733-1812). Sister-in-law of Robert Brown.
Life with Boswell:
Boswell first mentioned her in one of his french themes of November 2 & 3, 1763, where he complains about the conditions of his breeches, and subtly suggests that she mend them for him. In this theme he also mentions the two playing Shuttlecock, an old original form of Badminton, and in a letter of November 26, 1763, Guiffardiere mentions (perhaps ironically) envying Boswell the joy of playing shuttlcock with la belle sæur (Margaret) an hour every day.
