Genesis 4:17-22 Raising More Cain

I realized after ending the post on the information about Cain in Genesis 4, that I had not continued to explore the rest of the line of Cain which is outlined in that chapter. When we left Cain, he had built a city. He named it after his son Enoch. Cain's family tree would look like this if we put it in visual form:

Adam
Cain
Enoch
Irad
Mehujael
Methushael
Lamech

Now Lamech marries not one but two women -- Adah and Zillah.
Adah's son is named Jabal. Zillah has two sons: Jubal and Tubal-Cain. Tubal-Cain has a sister named Naamah.
