The Rulo cemetery listings don't give a death date for Amelia.She has no stone, but the records give her birth year as "1829?"The Censuses I mentioned earlier give her birthplace either as Missouri (1860) or as Dakotah (1870).
Information on Charles is also lacking. His death is listed as "in the 1870's."Since newspapers in Richardson County at that time were few, I have been unable to narrow it down.Do you know his date of death?Several other researchers here also haven't been able to find it.
