Nehemiah Gregory III lived with a grandmother in Norwalk, CT during the Revolutionary War (while his brother Jehiel was fighting in NY). He was living with her 1779 when Tryon made a raid on Fairfield and Norwalk, after which he also enlisted even though he was underage. His paternal (natural) grandmother died in 1745-49, but this could have been either his paternal stepgrandmother (Elizabeth Trowbridge Saint John Gregory) or a maternal Barnum grandmother.
