Vallance arrived in Philadelphia from Glasgow Scotland early in 1791. He quickly established his reputation as one of the best engravers in the city. During this period he developed a friendship with James Thackara. In 1791 Vallance married Elizabeth Trenchard, a niece of Thackara's wife Hannah. A partnership with Thackara was established. He engraved banknotes and documents. In addition he was one of the founders, in 1774, of the Association of Artists in America. His wife Elizabeth died in 1798 at the age of 28. Four years later he married again to Margaret Pratt.

Middleton, previously a captain in the employ of The Hudson Bay Company, was financed by Arthur Dobbs to explore the north-western extremities of Hudson Bay in search of a north-western passage. The expedition, from 1741-42, should have disproved notions of such a passage, but the increasingly delusional Dobbs convinced himself that Middleton had deliberately falsified his findings, and mounted an attack on the captain’s integrity, using a series of rather dubious maps distorted to support his viewpoint.
Middleton’s chart over Hudson Bay, published before the eruption of the controversy, is of great importance as the attempt at an accurate survey of the west coast of Hudson Bay (Cumming et al, Exploration of North America, p. 188), and the only reliable printed cartographic record of the captain’s discoveries. Surprisingly, the chart was not included in Middleton’s book defending his reputation, and is now rare.
