	His father, Richard Sanger III (1706-1786), continued in the blacksmith business and married Deborah Morse . Sanger III inherited a sizable fortune from his father in 1731, which he enlarged through a lucrative trading business in Boston, real estate speculation in Maine, and operating a store and tavern in Sherborn. The family was one of the most prominent in Sherborn's history, and a house he built is listed on the National Register of Historic Places as the Richard Sanger III House. After living for a short time in Boston, he returned to Sherborn in 1748, purchased a large property and continued to trade in merchandise, lumber, and land.
