I have just seen this post and thought I would look it up for myself. This is what I have found.

Linus

The boy's name Linus is pronounced LYE-nus. It is of Greek origin, and its meaning is "flax". From Linos. Biblical: a Christian companion to Paul in Rome. Greek mythology: Linus is the musician son of Apollo.

To me it is saying it has a christian meaning and I was sure that so did the name Jacob.

Jacob

The boy's name Jacob is pronounced JAY-kub. It is of Hebrew origin, and its meaning is "he who supplants". Biblical: the son of Isaac and Rebekah and twin brother of Esau. Jacob fathered 12 sons and a daughter, who became the ancestors of the nation of Israel, the name Jacob himself received after wrestling with an angel.

What I found most interesting was that Jacob and his children became the ancestors of the nation of Israel. I think that Ben is trying to create his own nation on the island just like Jacob. Hence why he is so determined for the women to be able to have children.

I don't know whether it is true it's just my opinion.
What do you think?
