I too am descended of HGM. I recently posted a picture on ancestry of Solomon Terrill May from 1927 that has notes about HGM non-churchyard burial near Metropolis, Ill. I have been doing heavy research into the possibility he is a Choctaw with parentage coming through Henry Co., Tenn from Mississippi Choctaw Nation per Treaty of Dancing Creek 1830ish. Me- with a variable suffix like - tubbe can be source of shortened May for Americanization. My Murrie and Ridge lines also appear tied to Cherokee Trail of Tears passing through Tennessee at same time.
