Gisli Sursson's Saga

I happend to notice the significance of Thor in Norse culture. Given that Thor is one of the Primary Gods, and that Thor's Hammer is a relic. I get the sense that Thor was a major god, if not the top god in norse mythology. This is because alot of the people in the sagas are call Thorstein, Thorgrim, Thorodd, Thorkell and others which I didn't bother to highlight. Which brings up the question, how much does the mythology play a role in the soceity? By the fact that many people are named after a God, I would venture to guess that the Gods played a huge role in society, whether it was superstition and that If I name my son after Thor, he owes our family good luck, or whether it was the cultureal Norm at this time, I do not know.
