There was an Andrew Hammerly who signed a petition to congress Feb 20, 1801. "sent to the Senate and House of Representatives by the subscribers, settlers on the publick land between the Waters of Muskingum, and Sciota River, in the Northwestern Territory." Found in the Territorial Papers of the United States, Volume III, the Territory Northwest of the River Ohio, 1787-1803.

I think it had something to do with land speculators holding up the process for settlers to get land. I don't have any other information.
