Old English Naming Patterns

Here's something interesting I found on the web that might help me figure out why children received the names they did in my ancestral tree:

The first son was named after the father's father.
The second son was named after the mother's father.
The third son was named after the father.
The fourth son was named after the fathers eldest brother.
The first daughter was named after the mother's mother.
The second daughter was named after the father's mother.
The third daughter was named after the mother.
The fourth daughter was named after the mother's eldest sister.
