"The various BSD OSes have a direct lineage to the BSD Unix developed at the University of California at Berkeley, and I doubt you can find anyone who would claim that the UCB Unixes weren't Unix. Lineage doesn't necessarily mean anything, though.
Linux definitely doesn't have any Unix lineage; it pretty much sprang forth fully formed from the head of Zeus Linus.
If you're interested in lineage, this history of Unix is interesting.
If you're interested in being able to say ""UNIX"" on the package, here is the list of products certified as UNIX by the owners of the trademark:
