According the the Historical Atlas of Alabama volume 2, there are 2 Upton cemeteries in Alabama. One is in Etowah county. The book says there is no evidence of any graves but it is shown to be near Hwy 431 near the Etowah county and Marshall county line.
The other Upton cemetery is in Marshall county. It is not plotted on a map but is listed as being on the J.F. Smith place on Merrell Mountain. It says there are only 3 graves: William Upton (1828-1882), Alva Dean Upton (b. & d. 1900) and Mary Yoma Willbanks (1906-1907).
Hope this helps.
