I would like to know if the same man signed 2 documents.  He is not a famous person, but is an ancestor of mine.  Both of these historic documents are owned by a state archive.  I have only scans/photocopies and I need the information for genealogical purposes.  

The first signature (top document) was on a petition dated 8 June 1781.  If it is the same man he would have been 57 years old when he signed.  The second signature (bottom) is on the man’s will dated 14 years later on 22 September 1795.  At that time he stated that he was “sick of body” and he actually died 8 days later on 1 Oct 1795.

I sent it to JSA, but they said it wasn't something they would do.  Does anyone know of a company or "certified" person who would give an opinion?
