According to some research a cousin sent me, Mansfield ANDERSON was the son of James ANDERSON. My cousin found this in the LDS, so I'm not sure if this is reliable or not. I can, however, send you the file (or you can view it online at the URL below) and let you evaluate it for yourself. The file traces James' ancestry back to the early 17th century. You may find it interesting but, again, I cannot vouch for it's accuracy.
