My 2nd great-grandmother (Jennie Elizabeth Markam) lived in Hamilton, Caldwell County, Missouri from 1870 to 1881 (potentially later) based on US Census records (1870, 1880) and marriage record (to my 2nd great-grandfather, Albert Hebert Bennett). In the 1870 and 1880 census she is listed as Jennie Esteb since her mother (Elizabeth) married Issac Esteb.
I am trying to locate the newspapers for Caldwell County and specifically the town of Hamilton for that time period. I found a reference on the Hamilton, Missouri wiki site that indicates the "Hamiltonian" and "News-Graphic" are the two papers for that time period. I'm looking for locations that have hard copies, microfilm, digital copies of the papers I can review. I am not located in Missouri.
Any suggestions are appreciated,
