I am searching specifically for info on the death of L(Leroy) B Parish (Parrish) of Chester County, SC. He served in Company B, 15th Battalion SC Heavy Artillery from April 1862 to June 1863. I have his CSA military records from the National Archives. The records indicate that he died in May or June 1863 but not where or when. His wife, Rebecca, filed for a pension in January 1864. Any help will be appreciated.
