Aligned with the wool industry the leather industry also thrived in Newton Abbot as shown in an agreement in 1580 between John Hayman and Richard Haymen. Another family which helped the leather trade to flourish were the Vicarys. The industry was still thriving circa 1800 when Moses Vicary was married to Rebecca Duke, a daughter of a wealthy boot and shoe merchant and the Vicary families helped the town to prosper, despite the ceasing of the manufacture in Newton Bushel of serge by 1805.
In 1739 the government debated the removal of export duty on Irish wool and cloth and several citizens of Newton Bushel sent a petition protesting against the removal. Following this the Vicary Family became involved in the wool industry and influenced growth. In 1786 after the death of Vicary his ten year old son and wife continued the wool trade.
