Though Samuel later made his home in Dover, he always maintained close business connections with the city, where he was a partner in the mercantile firm of Baynton, Wharton and Morgan.
There Wharton represented a group of merchants, known as the "suffering traders", who had had trade goods destroyed during the French and Indian War and Pontiac's Rebellion (Marshall 1965:717).
Wharton served two years as a state court judge in Delaware before retiring to a country estate just outside Philadelphia, where he died in March 1800.
