I can't help you with any information regarding these 4 soldiers but I'm hoping you can help me. I have been trying to find the date of death and final resting place for Pvt. William B. Malone who was in Company L, 15th Regiment, Mississippi Volunteers. He enlisted at Grenada on Oct 26, 1861. His final Company Muster Roll for Jan 1 - Apr 30, 1862 shows him as "Missing since Apr 7, 1862". I understand his unit participated at the Battle of Shiloh and April 7th was the 2nd day of the battle. So, I'm wondering if he could be one of the 31 unknown soldiers buried at Oakwood Cemetery in Winona.
