First,Richard S. Hess as an interesting post up:
The genealogies of chapters 4, 5, 10, and 11 are filled with personal names. Of course, the main characters, from Adam and Eve to Abram and Sarai, are also named. The names are often overlooked by modern readers, but not by the ancient Israelites who understood Hebrew. Many of these names were important on several levels. Let us consider, for example, the name, Adam. It is not until Genesis 4:25 that it occurs for the first time as a personal name.
