[2] Scull was one of the twelve original members of The Junto, "a club for mutual improvement" founded by Benjamin Franklin in Autumn 1727.
He handled land disputes in the Delaware Water Gap region between Dutch, French and early Pennsylvania settlers.
He accompanied Surveyor General Benjamin Eastburn on the notorious Walking Purchase of 1737,[2] a "land swindle,"[5] through which the Penn family claimed an area of 1,200,000 acres (4,860 km2).
[2] As Surveyor General, Scull published multiple maps of the Philadelphia region, working at times with his wife's relative, George Heap (c.1715-1752).
Together they had a daughter, Mary; and three sons: Edward, John, and Nicholas III, who became surveyors.
