My wife has several relatives buried in the Kenedy, Texas cemetery who were civil war veterans. Her dad could remember them and tell their stories. Not that many generations separate us.
At my rural church cemetery in Southeastern North Carolina we have many Confederate veterans, and also a slave burial section. In addition we have a Revolutionary War veteran buried there as well, who fought with the 5th NC Regiment. He was born in Scotland and died in 1812. (The church was founded in 1801) A veterans memorial group helps maintain the graves and stones of all veterans, and keeps them marked with the appropriate flags year round.
