I think that this grave marker belongs to James A. Warren, son of Owen and Rebecca Warren, but I can't be certain. Based on census records, this family is the closest match to the initials and dates found on the marker.
The grave is located on private property in northeastern Itawamba County, and is only one of two graves with markers although several more graves are believed to be in the area.
Son of O. W. and R. E. Warren
Born March 15, 1867
Died Nov. 14, 1901
Too good for Earth, God called him home
Odd to me that the grave marker is adorned with the image of a little lamb when the son was 34 years old at the time of his death. Maybe he was disabled?
The 1880 census has the following household in the First Supervisor's District of Itawamba County:
Owen Warren, 54, black male, born South Carolina
Rebecker, 30, black female, born Alabama
Mary E. 16
James 13 (I think that this is James A., born 1867 per the headstone)
I can't find this family in the 1870 census, but some parts of that census is missing for that side of the county. S. John Warren was a large landowner in early Itawamba County. He and his several sons were also slaveowners, and as a consequence there are several black Warren families in the post-Civil war period in Itawamba County.
