Sometime before 1775, Honeyman moved to Philadelphia and supposedly met George Washington who was attending meetings of the Continental Congress. Although Honeyman had served the British well during the French and Indian War, he was sympathetic to the American cause and promptly presented his services to Washington. Washington, astute at finding good talent, accepted Honeyman's services. In the early part of 1776, Honeyman moved with his family to Griggstown, in Somerset County, New Jersey. It is unknown, however, whether this move was a result of his meetings with Washington.
