Llanview was founded in 1820 by Cyrus Quimby and Thunder Quartermaine as a mining town. It is younger than Springfield and Port Charles, even more so than Pine Valley. Llanview's original name was Prairie Meadow Hill, due to the fact that it was once a prairie meadow.
An overwhelming majority of the first inhabitants of Prairie Meadow hill were possibly Poles from the slowing Russian empire. They didn't even speak English, which meant that an army of north Welsh workers came in handy.
In 1836, It got renamed as Llanview and the name stuck because of the Welsh workers. More and more European people, primarily Ashkenazi Yiddish, Westphalians and Bavarians, immigrated to Llanview via Ellis Island throughout its early existence.
