Just a little more info I had but didn't realize I had:
Catherine Anderson b: 1833-01-12 d: 1870-12-12 in Medoc, Jasper county MO m: 1851-08-07 in Pickaway county OH to George Richard Grove (son of Henry Grove ii & Martha Ann Fleming) b: 1827-12-05 in Pickaway county OH d: 1910-06-22 in Mansfield, Piatt county IL buried: Mackey cem. Piatt county IL
Once again, what I'm trying to find/confirm are Catherine Anderson's parents (ancestors), birth-place and burial place.
A couple familysearch IGI records had them as John Mendenhall Anderson and Elizabeth Hays.(Haven't found them, but we found, in Jasper county MO a John Mendenhall Grove and Nancy Moiselle Willoughby, and their vital dates don't match up, nor do we have info on their immediate relatives to see if there are any indirect connections.)
