Alexander was the fourth son of John Tennant and Margaret McClure . His father, a farmer, was well known in the industry. 'A worth, intelligent farmer, my father's friend and my own', was how Burns described the prolific John Tennant of Glenconner in a letter to his lover Clarinda, dated 2 March 1788. This work ethic was found throughout the family; his brother Charles becoming a highly successful industrialist, his brother William the Chaplain to the Honourable East India Company and a further brother, David, a noted privateer.
