This is interesting and good information to know.  At least it used to be when I was growing up!  But it can be more than a bit complicated.  My first cousin from California sent me a diagram in the mail quite a few years ago, explaining basically the same things but I have no clue where to find it! So I was glad to find this this online chart.

Luckily, there's a more diagramed chart as you scroll down into the article.
