Greenbank House: Tobacco and Slaves

Robert Allason began his working life as a baker then, on moving to Port Glasgow, started trading goods and finally became a tobacco merchant. He and his brothers, Sandy and William, traded in tobacco and slaves. His brothers placed themselves at key points of the 'triangular trade'. Robert also had connections in Liverpool and London.

In 1760, Robert created his own tobacco company with William. By 1765, he owned a Glasgow mansion and built a new country villa, outside of Glasgow, called Greenbank House. However, the American War of Independence (1775-83) disrupted his business and, by 1780, he was owed around £10,000 (worth almost £1million today) which he never received. Robert went bankrupt and lost Greenbank.
