Well I found out today that Ham is the youngest of the brothers. :)
In Chapter 9 verse 20 Noah got a little carried away with the wine from his vineyard. He fell asleep naked in his tent. Well, Ham walked in and saw him. So he told his brothers about it. They walked in backwards with a garment over their shoulders and covered him up. Then ...
Genesis 9:24 "When Noah awoke from his wine and found out what his youngest son had done to him" (emphasis mine). He then cursed Ham's son Canaan. Which I don't think is fair but that goes on the list of 'Who am I?' Boy, embarrassment is rough.
So, I now know that Ham is Noah's youngest boy. This is exciting.
