This document contains the signature of a Revolutionary War soldier.
These are two bond documents, one from 1784 and the other one from 1793, with one in English and one in German - between Jacob and Andrew Kauffman. Jacob Kauffman (1727-1812) was in debt and bound himself, his heirs, etc to his nephew Andrew Kauffman (1760-1845) first in 1784 and again in 1793. The first bond (In German) was paid and the signature and seal of Andrew Kauffman (Kaufmann, Coffman) was cut out in order to make the bond void or paid off.
