Thomas Mewburn was a clerk who worked in Demerara from at least the 1790s, becoming the attorney for Thomas Cuming’s plantations by 1799 [see letters from Cuming to Mewburn in Warrand of Bught papers in library]. He became a leading figure in the colony as captain of the 1st Battalion of the Militia , a financial representative on the governing body of the colony , and chairman of proprietors in the new town of Cumingsburg . He acted as an agent in Demerara for Campbell & Co of Glasgow.
Mewburn appears to have left Demerara in December 1815 (or early in 1816), travelling with a servant, and again in 1817. His daughter Anne married in Liverpool in 1816 [Liverpool Mercury] and his African-born servant, George, was baptised there in 1818. In 1819 another daughter, Catherine [b1797], married Alexander MacAlister, from Skye, a surgeon in Demerara. Catherine’s mother was a Johanna De-Brugh. Catherine Mewburn died in Australia in 1872.
