Benjamin Scott, 1784-1862

Benjamin Scott was a tailor in Decatur Twp, Mifflin Co, PA. In his will, he left $1 to his son, Alexander D. Scott. Alexander D. Scott was b. 1810, but the only known marriage of Benjamin Scott occurred 17 Mar 1818, when he married Eleanor Bell in Belltown, Mifflin Co, PA. It seems pretty obvious that Benjamin had a previous marriage. My question, should you care to answer it, is who was Benjamin Scott married to between 1800 and 1810?
