Here in San Antonio we have Ft. Sam Houston National Cemetery; I am not certain whether it is as old as the post, but I think it is very near. My grandparents are buried there (as will my mother be, when she passes away). I learned quite by accident that there is another national cemetery in the city. If memory serves it is called San Antonio National Cemetery. Most of the graves in this one are circa 19th century. There is also a Confederate cemetery not too far from that national cemetery. Though a handful of people who fought in the Civil War are buried in SANC, far more are here of course. If anyone is interested (I realize it is a somewhat esoteric topic), I have a few photographs I can share of both cemeteries.
