You have helped alot, if im understanding correctly by what you found.... Arthur and Zachariah both marred a Dora (Tulla) L Price, 5 years apart in same county. Arthur married Tulla L Price Sept 2, 1883 (had Samuel, 1884) and Zachariah married Dora L Price Dec 24, 1888 which would explain why Samuel is on 1910 census as step son. Now to find Arthur's death or divorce? Thank you
