Notes for William Royal HOPPER: Jane, Phoebe and William were buried in Little River or Lyons, KS (Reference Mrs. Arthur O. Ball, 219 Pinedale Ave., Oroville, CA 95965).
Same reference found a sheet of paper in Helen Lull Smith Hopper's Bible stating that William Royal Hopper was born in 1846, then it was crossed out and read 1843 and he died in 1845. Since there were 2 years between each of the girls, but five between Jane and Martin Luther, there is speculation that Jane and William may have been twins or that he was born in 1846.
