By the early 15th century, the manor of Kentwell belonged to the Clopton family. John Clopton was arrested in 1461 and charged with treason. Clopton was spared execution and he was released and returned to Kentwell. There he organised and largely helped to pay for the rebuilding of the parish church, a notable example of a wool church. During this time the wealth of the parish was increasing, with most of the inhabitants being free men, renting their homes and lands. Guilds were founded, and weaving cloth became a key part of the village's economy. In the official inspector's returns for the year 1446, there were as many as 30 named weavers in Long Melford, who between them produced 264 finished "cloths".
