Interesting. Thank you for posting this. Longacre's biography, Pickett, Leader of the Charge, does include a few pages that mention "Jimmie" James Tilton Pickett but I was surprised to read in the article that "Pickett's good friend, Sam Grant," whom I"m assuming is Ulysses S. Grant, also is believed to have married an Indian woman who took the Christian first name of Caroline, while stationed in Oregon Territory. I went back and looked up "Caroline Grant" in a number of my Grant biographies and came up with zilch.
