I am a weaver. There is a overshot pattern called the IRISH CHAIN. I will give you this reference from the university of Arizona:
http://www.cs.arizona.edu/patterns/w...hs/tl_kcov.pdf
The information contained there isn't much, but I can remember hearing from my grandmother that it is a pattern that is older than the hills. She claimed she learned it from her grandmother.
You could probably do some more digging if you went after the weaving angle.
Good luck - it was an interesting question!
