The BSD 4.4 log-structured file system is the earliest CoW FS that I know of, though the ideas really go back earlier to the database world. (There's a tremendous amount of duality between databases and filesystems, so much so that it's pretty shocking that they haven't quite merged. WinFS should not have failed.)
I think of ZFS as a direct descendant of the 4.4BSD LFS, though I don't know that it is so -- in fact, I suspect Bonwick et. al. did not take inspiration from 4.4BSD LFS, but came up with a filesystem that looks inspired by it.
