Thanks for your interest. I've done more investigation since I first posted:
The USGS National Mapping Information lists a Dorig Post Office (historical) in Richland Parish in the Gillyville Quadrangle.
I've also located the Girod Cemetery, on the river in Caldwell Parish, Latitude: 32.1652, Longitude: -91.9818.
And there's a Girod Lane somewhere upriver from the cemetery, but I can't remember the town.
