Here's a link to a great site that I think will help you.
http://www.cliburnfamily.com/pafc05.htm on the page hold the Ctrl button and hit F then type in "pianist" into the search box. you can also start from page one to follow the line. Van is the son of Harvey Lavan Cliburn, son of John Marshall Cliburn, son of James Barnes Cliburn, son of John Barnes Cliburn. I'm also trying to get more information (before John Barnes Cliburn). My great grandmother was John Marshall's sister Mary Amanda. My grandmother was Josephine Baklin. Feel free to e-mail me at angelhologram at bellsouth dot net (obviously change the at and dot to the symbols @ and . just typed it that way to keep away spammers). If you come across any info before John Barnes I would be very interested.
