Checked Ancestry Civil War info and found both men and enlistment/discharge info. No burial info. Winegar was on the 1890 Vet census as was Johnson, but it did not state that John E Johnson had died or list a widow.

I checked the cemetery records for John E Johnson and found a burial in Seaman Cemetery for
Margaret Johnson wife of John E 1852 - 1924.
No Burial for him in that cemetery. There is a Johnson cemetery but there is no info as yet. If no success, then send for his military/pension records from the National Archives.

As for James A Winegar - Hilton Cemetery Casnovia,Twp., Muskegon MI

James A Winegar Cpl 9 MI Inf 2 Aug 1838 16 Sept 1893

Don't know if this is a military headstone. But military info checks with info on Ancestry Civil War info. No other Winegar buried near him.

Check this website it is very helpful.
