His service from Heitman1 and Cullum.2 His Cullum number is 1656. His picture from Uriguen.3 Personal details from family genealogists. His gravesite is on Findagrave.
Heitman and other sources have his middle name as "Duff". That was probably his son's middle name. Thanks to g-g-grandaughter Susan Ohman Baldwin for helping us get this right.
He married Catherine " Kate" Rich (1840-1880) in October 1859 and they had 12 children between 1860 and 1880. Oliver does not seem to be directly related to General George Sears Greene. Oliver's father was George Saunders Greene (1786-1875).
