***Some people claim that John was born around 1740, and he died in 1790. But John was definitely born before 1740, because it is known that he was born in Germany, and it is known that his parents sailed to America in 1740. (His father's name was on the 1740 passenger list for the ship "Lydia.") Furthermore, John definitely died after 1790, because he was seen on the Tax Lists, up through 1793. His will was recorded in January of 1794, because he died in January of 1794.

***Some people also claim that John had sons named John Back (1760-1845) and Jacob Back (1764-1839), but John only had daughters, as proven by the Tax Lists and other documented evidence. Those two other men were actually John's cousins (sons of his father's brother).
