Would that be Private George Hurst, Co. G, 12th Texas Cavalry?
There was a brick church, Methodist-Episcopal South denomination, a few miles up the road from the Yellow Bayou battlefield where a lot of the Confederate casualties were buried. George would have either been buried on the battlefield or at that churchyard. My bet would be at the churchyard, as that is where Capt. Weir of that same regiment was buried. The church was burned or dismantled long ago, probably back in the 1880s, but the cemetery was around up until the 1930s. Some of the old-timers around here remember playing hide and seek around the graves, but that cemetery was buried under a levee back when all the flood control projects were under way after the high water of 1927. The site is known, but there's nothing there but a levee and a field. The farmer who works the place occasionally plows up pieces of tombstones, but they would be from the local people, as the soldiers would only have had wooden headboards which rotted away a hundred years ago.
At any rate, the cemetery is in the community of Hamburg, along La. Hwy 1, on the Dubroc property just east of the old Calliham plantation house. If you stand on old Hwy 1 where the levee comes up to the road, you should be within a few hundred feet of George's grave.
