Two studios with the same name

The four pictures below were produced by TriState Pictures, a motion picture studio in Cleveland, Ohio. https://case.edu/ech/articles/t/tri-state-motion-pictures There is another, more recent studio by the same name. Can you help me assign the films below to the correct studio? Bill Howard, R.F.D. (1937) The story of a farm family's struggle between the old and the new.
