By the age of nine, Henry was able to write Latin and read part of the Greek new testament. He was tutored in grammar by William Turner in 1668 who was temporarily staying at Broad Oak. His father provided much of Henry's early education at home. Henry practiced writing by copying his father's sermons and as a child he exhibited a natural public speaking ability. In 1680, at eighteen, his father sent him to a school in Islington, London to be tutored by the Nonconformist minister Thomas Doolittle. Henry later transferred to Gray's Inn, in the heart of the capital, to study law. While at Gray's Inn, he also studied French and literature. He soon gave up his legal studies for theology. Henry was invited by his friend George Illidge, to give his first sermon to a congregation at Nantwich. Having been well received he returned to speak two more times that summer.
