Despite growing up in a Civil War battlefield town, I am pretty dumb on US history. But, I do know the name Sumner Moore, but not WHY ? Who was he and his descendant Sumner Moore Kirby, first husband of G. D. Leonida, mother of G. D. Maria V. "curatrix" of the Romanov throne? And, why did he die in a Nazi concentration camp ? [he was American, I presume].
