I'm not convinced that I'm completely on top of what this list is about but it's a promising beginning. I hope it develops further and that I learn some more.
also hail, as in "Hail, Caesar!" and, for the Christmas season, wassail, from the Old English wæs hæil, "be in good health".
I stumbled across this and realized what I was seeing when I was studying Afrikaans - though now I can't recall exactly what triggered my realization that whole and heal are cognates with overlapping meaning. In our New Age philosophies, we see "oneness" and healing and feeling whole and... OK, this is a stretch... healthy foods like organic, soy-based granola. That last one can't be a real connection, but it was fun.
After that, hale, heil and holy (but not holey - an antonymic homonym) were the most fun to link.
