This document is courtesy of Paulette Gilchrist; it is a receipt record for court testimony for several Washingtons, including Darlington and his father Thomas Washington. Darling's is evidently an actual signature; Thomas's might not be, for it appears to be in the same hand as John, below Thomas. Paulette notes that "this old book was just found (May 2006) in the old courthouse in Ashville, St. Clair Co. (where Ashville is one of the two county seats). It is a Sheriff's Record Book. Witnesses had to sign that they had received their fees for testifying in court. Darling could write, Allen could not and I believe the same person signed for Thomas and John." Thanks, Paulette for this valuable record!
