Well, this much can be confirmed --
Henry C Jordan, Co F, 5th (not South) Alabama Regt. You can see correct dates on the stone. A marker for Mary Elizabeth is not recorded at Hopewell Cemetery. It appears that they moved to Wise County TX about 1878; not sure when they returned.

If Mary Elizabeth lived in Pensacola as a widow, we could expect to find a Florida pension application in her name.
