Ken Ives recently sent me this material through a comment and I wanted to elevate it to a post so it would be more accessible. It is much appreciated. What follows came from Ken.
There's an article in the spring edition of the National Archives' "Prologue" magazine that Ives researchers may find interesting. It is titled "All for a Sword: The Military Treason Trial of Sarah Hutchins". There's an on-line version of the article at the above link While the article focuses on the treason trial of
Sarah Hutchins, a Baltimore woman, near the end of the Civil War, it also discusses briefly the closely-related treason trial a New York stock broker named William Ives. This was William Jay Ives, b. abt 1833, son of Ansel Wilmot Ives. Though he was from New York, his family straddled the line during the war. His brother, Joseph, was a Colonel in the Confederate army, and an aide to Confederate president Jeff Davis.
He had another brother, Leonard, also in the Confederate army, who was mortally wounded at Gettysburg (and figures in the article). A third brother, David, served in the Union army. And finally, his brother Malcolm Ives was a war correspondent for the New York Herald, who was at one point charged with spying and imprisoned for several months, then released without a trial.
Ken also posted this on Ancestry, but your site may reach a somewhat different audience. He thinks it should be publicized because it is, as far as he knows, a completely unknown chapter in our family history. The research backing the article is quite good, done using primary sources, by a professor of history at Christopher Newport College in Virginia, and it fits perfectly with other information my own research has found on William Jay Ives and his siblings. He closed by thanking me ever so much for hosting this site, and especially for bringing Richard Ives' great work on the early Ives family to the rest of us.
