I'm very glad you've found where it is located. Alan would be the one who would know.
The sad fact on some of the graves that are in areas such as Pollard and other rural places is they may be gone. I have been reading an account of life in North Escambia County in the early 1900's and there's a number of references of graves being discovered when farmers were clearing for planting. Some could have been Indian, early settlers, trappers or soldiers. No way to know.
I'd like to believe most of them did what the account said happened to one, moved the bones and little marker to a family plot down the highway. I'm not sure that was always the case. There's a number of times I've heard of the grave being plowed over. I hate it when that happens. It's just not right to my way of thinking but there's people or entities like the US Government who thought it was just peachy to build a parking lot over the grave of the engineer who built Ft Barrancas, Ft Pickens and Ft McRee. Yep, asphalt. No marker.
In our area, there are stories of graves in odd places because the Union was pretty steady on the tail of the few Confederate troops trying to get out of dodge. Many were wounded and died and were buried where they fell. It was the only thing they could do.
