According to the Boone Family history, Boykin Witherspoon's son, Gavin Witherspoon (named after his g-grandfather) married the ggggg-niece of the infamous, Daniel Boone on May 10, 1862 in DeSoto parish, Louisiana. Her maiden name was Flora Rubey Vivian. Her great-great-great grandfather, George Boone was Daniel Boone's brother. Their father was Squire.
Gavin and Flora Vivian Witherspoon relocated to Hollywood/Los Angeles, California.
Gavin and Flora's children were: Gavin Witherspoon, Jr., Gwendolyn Vivian Witherspoon, and Jack Vivian Witherspoon. All born in Hollywood, CA.
The history also states that the Witherspoons were descendents of John Knox the Divine pictured above. I did in fact verify through the LDS Family site that Boykin was indeed a descendent of John Knox the Divine of Scotland. See post entitled, Boykin Witherspoon, descendent of John Knox the Divine for detailed lineage.
