The only census data I have is from 1880. It only shows two children of which Mellisa is one. I'll try to research more and get back to you. I do have a copy of the death certificate of one of James & Mellisa's children (Sol) which does list him as one of nine children. Let me know if you want a copy or the names listed as sisters and brothers.
I'll try to get back to you on Ruthie.
