Hi I am looking for information on John Hays b. 1822.

What I know is that he:

Married Mary Rhia Jan 3rd 1843 (Ray on the 1850 census)
Resided in Division 9 Greene, TN
Civil War Records indicate that he was a member of the Union 8th Tennessee Cavalry. Rank- Wagoner.
Moved to Scotland County Missouri sometime before 1880
Died Jun 5th 1884
Does anyone have any information on this family?

Thank you,
Eric Hays
