Aaron served in the New Jersey Militia in Lippencott’s place after Lippencott was drafted in 1777. Aaron was assigned non-combat duties, due to his Quaker beliefs, and served as a spy and a teamster (a person who drove a team of animals pulling a wagon). Even though he never saw combat, Aaron was not allowed membership in the Quaker Society of Friends, since he participated in the war.
At the age of 20, Aaron married Mary Archer on May 4th, 1779. During their 17-year marriage, Aaron and Mary had nine children. Aaron and his family moved to Kentucky in 1788, along with his brother-in-law Benjamin Archer, then they all moved to Ohio in 1799. A brother-in-law already settled in the area, Benjamin Robbins, offered to store Aaron’s family’s possessions and let them stay with them while they built their home, but Aaron responded with, “I am not going to unpack until I enter my own cabin” and with help, built his new home in just one day.
