To Johnson Researchers, Just a recommendation, verify the information on Sir John Johnson and Clarissa Putman before using it. To my knowledge they were never married. However they had 2 children: Margaret (m. James E. Van Horne) and William, b. 1770 at Fort Johnson, Montgomery County, NY. ( m. Margaret Clark). Sir John m. Mary (Polly) Watts in 1773 in NYC. They returned to Fort Johnson. Clarrisa and her children had moved out. Sandy Allen
