Keith, all I could find is basically the same as what you quoted...here's a little more.
The Cross Keys Plantation, comprising approximately 1,453 acres, was acquired by William W. Watson, husband of Anna McCall Watson, from Thomas R. Sutton and Thomas B. Kempe on November 15, 1853, for $52,000. At least a portion, if not all, of the main plantation residence existed at the time of the sale. The name "Cross Keys" was given to the plantation at the time of its purchase by Mr. Watson and his partner, Dr. Asa P. Jones, who was his brother-in-law, being the widower of his sister, Olive, who had died in 1848.
William W. Watson was the son of James H. and Anna Maria Cable Watson who owned the Waterloo Plantation in Jefferson County, Mississippi. William W. Watson and his father-in-law, Dugald G. McCall, had previously acquired the Clio Plantation, just across the river from Rodney, Mississippi, and apparently lived on the Clio Plantation at the time of his purchase of Cross Keys. Clio Plantation has since been taken by erosion of the Mississippi River.
