I am interested in my great-great grandfather Richard Cary Robertson. He lived in Missouri and died at the end of the Civil war and died when the CSS Kentucky sank at Shreveport La.What information is present about his forebears, especially "Scotch Will" Robertson and his Scottish roots. He presumably migrated to Chesterfield County, VA in in the 18th century. I understand the Laura P. Robertson has some information on the Scottish ancestors. I will try to obtain a copy of the book locally, but would appreciate any information you can provide. Thanks, John Marsh.
