My gg-grandfather Sergt. Joseph D. Porter b abt 1834 OH was a member of Co B, IL 104th Vol Infantry and killed by a musket ball 7 Dec 1862 at the Battle of Hartsville, TN. He resided Tonica, LaSalle, IL when he enlisted. His widow Sarah (Bascom) Porter and 4 children resided Tonica, IL 1863, but children were born in both Tonica and Magnolia, Putnam, IL. Sarah's pension app includes an affidavit from Capt. Samuel A. Porter of Tonica, IL, same regt and co, who attested that he was present when Joseph Porter was killed. I suspect Samuel Porter's grave is at Sparland Cemetery, Marshall, IL [IL on-line Roll of Honor], but I've not located a grave site for Joseph D. Porter. I'd like to find out if Joseph D. and Samuel A. Porter were brothers. Also would be pleased to know the final resting place for Joseph D. Porter. Any information or assistance would be wonderful.
