Captain John Mason (1586–1635) was an English sailor and colonist who was instrumental to the establishment of various settlements in colonial America and is considered to be the 'Founder of New Hampshire'.
He was appointed the second Proprietary Governor of Newfoundland's Cuper's Cove colony in 1615, succeeding John Guy of Bristol, who had resigned.
Published in William Vaughan's Cambrensium Caroleia in 1625, the map included previously established placenames as well as new ones such as Bristol's Hope and Butter Pots, near Renews.
His tract entitled A Briefe Discourse of the New-Found-Land with the situation, temperature, and commodities thereof, inciting our nation to go forward in the hopefull plantation begunne, was published in 1620 by Mason while in England.
