Some sources, including "Biographical and historical record of Jay and Blackford Counties…" on page 746, incorrectly use the year 1867 as the date of incorporation for Hartford City. The Blackford County Historical Society’s "Blackford County History" pamphlet says the year is 1857, and the city celebrated its centennial anniversary in 1957 (not 1967). Records from the Blackford County commissioner’s book 2, on page 401, show 1857 is the correct year.
