When I finally found my great grandfather C.R.Hill on the only census I could find him on, the 1880 Census of Boone County, Rocky Fork Missouri, he was with his wife David Ann (Dunbar) Hill their only son at the time, Charles H. and also there was a Mary E. Hill (N.R.) 9/12. I do not know for sure what the N.R. stands for. But I sure would like to know where she came from, where she went. She was born in Missouri it says. Lena
