Interesting...I have never figured out how to look into who these Borderbund tree's belong to...Borderbund is just an old software program -- name has changed I think over the years, but they turn up often as a source, but that doesn't help any more than finding someone's tree on ancestry unless somehow they document the source. Will see if I can figure out how to access it and what vol 6 and tree # means? I think these ended up on some CDs that people bought and used before web-based trees existed. Hmmm.
