No, I don't have any additional information. The letter written by Berry was on July 4th, 1864, and does not mention the husband's name at all. The description by the Huntington Library has the title "Thomas R. Berry, letter to Minerva Sparks Reed, July 4, 1864," but no where on the letter have I seen the name Minerva Sparks Reed. The exhibit at the Huntington library had only part of the written letter.
