Thomas Brocas was a Methodist preacher and gardener of the late-18th and early-19th century. He is first known as working as a gardener at the Sansaw estate, Shropshire, from 1773-1786, where it seems he was often in trouble for neglecting the grounds. He then left Sansaw and became gardener to Mr. Wingfield at Whitehall, in Shrewsbury. To begin with his employment seems to have gone well, but the Wingfields fired him in 1789, as he was overly involved in preaching and did not properly tend to the gardens. He gave up gardening after this, and concentrated on religious activities. He is known in early-19th century Shropshire as an outspoken critic of Calvinist and Baptist views, especially on predestination.
