I represent the child of Mrs. Ross enumerated with her in the Return of Women & Children, 31st Regiment of Foot, Capt. Varlo‘s Company, September 1768. The 31st was an infantry regiment that arrived in 1765 and – with a brief transfer to St. Augustine in 1769 – remained until 1772. My father was not named in the Return, but according to the August 1768 muster roll of the 31st, it was Corporal Alexander Ross.
