Haines was born some time in early May 1633 at Sullington, Sussex, and died in London on 29 May 1685. He farmed at Sullington throughout most of his life, but despite an interest in agriculture and science, he seems not to have been a very successful farmer and had to sell land on several occasions. He was well known in London as well as among the gentry of Sussex, and seems to have had friends at Court. A polymath, he wrote on economy and trade as well as agriculture and science.
