I am really interested in the "Illinois Connection".Joseph Green was an uncle to William Frederick (my GG Grandfather).Joseph Green was in the 1st Alabama Cav USA. He died in Corinth. MS.Martha (Frederick) Green, Joseph's wife,is said to have died in Union Ill. , 1863.I have often wondered how/why Martha had been in Ill in 1863. Is Union Ill close to Marion Co. IL? Martha died while in Union Il in 1863.I would be interested in finding her gravesite. I have also wondered what was my GG Grandmother, Adaline (Tyra) Frederick doing while William was away with the 3rd Ohio Cav.Did she leave also?
