I have very little detail about them, in fact even the spelling of the name might be wrong. Beistline or Beistlin. The tombstone says Beistlin, but cemetery records and census records say Beistline. According to the 1880 US Census, John and Susanah were both born in Pennsylvania. They apparently moved to Iowa after 1854 and before 1862 then to Nebraska before 1880. Their daughter Sarah married my 3rd great grandfather, Samuel Hunt in 1868 in Downey, Cedar County, Iowa. So that gives an idea of how they got from Pennsylvania to Eastern Nebraska.
The tombstone is transcribed as follows:
Apr 16, 1904
Gone but not forgotten
Wife of J.R. Beistlin
Dec 30, 1885

The morning sun was at a low angle which
enhanced readability of this side.
