Glad to help. I am not familiar with Glass Mill. Do you know where that was on the battlefield? Even if he was buried on the battlefield, many of the amrked graves on the battlefield were exhumned and removed to Marietta. If he was killed with a battery, there were likely other casualties and it is likely that they were buried together and marked. The spelling errors were many because many of the "marked graves" were boards or parts of wagons or in some cases carvings in nearby trees.
