James Howard, son of Callie and James Samuel Howard married my Aunt Belle. None of their children moved to California. Elsie Mae Howard Robinson was the only one I knew well and she lived and died in Franklin Parish. My mother, Amanda Elizabeth, was the youngest daughter of Callie and James Howard. She married Alvie Alonzo Wyles. Callie and James also had a son Samuel (died before marriage age) and a daughter, Adelaid.
If your James had children that went to California, then this is not them, I don't think. Check my web page at http://wyles.freehomepage.com
