The ancestral seat of the Godolphin family was Godolphin House near Helston in Cornwall. The family took a close interest in mining and a number of mines were founded on their land. At Wheal Vor they experimented with several new inventions (for instance, the Newcomen engine in 1715) to improve the working of their mines.[2]
