Sketchy information in our family tree lists Abner Beckwith from Chatham NY as having 4 children: Silas S. Beckwith, Phoebe, Benjamin, and Abner. We have a date for Silas S. Beckwith of 1800. Silas married Elizabeth Paul and had 11 children. It seems possible that Benjamin could be the person mentioned in the will. If you find out any information I would appreciate it. Thanks.
