Pleasantview/theories

You know how Sunset Valley was the predecessor of Pleasantview? Well anyways I just noticed how the Pleasant Family wasn't depicted in Sims 3 even though they go many generations back. I also noticed that the Pleasant Family has their name in the neighborhood of Pleasantview. Could there be some patch of important history that has to do with the Pleasants with the founding of Pleasantview? Or did the Pleasant clan live in the area before the neighborhood's founding?

Theories

 * Everyone should remember that Gunther Goth founded the town in the original sims. So that is the same town. They just changed the name because many families had peaceful lives. Then the peace destroyers( Calientes and Don) arrived as stated in the neighborhood bio.
 * I think it's got something to do with the Landgraabs, you know. See, in The Sims 2's Pleasantview, the Landgraabs are not mentioned while in The Sims 3 (which is set long before Pleasantview exists) the Landgraabs founded the town with the Goths, if I'm not mistaken, while in The Sims 2's Bluewater Village lives Malcolm Landgraab IV. So Mortimer married Bella and had children, thus the legacy continues and the family does not die in male line. Malcolm, the only child of the Landgraabs, perhaps did not marry or had no children, thus the family line dies and the Landgraabs are never mentioned anymore. And the Pleasants are the family that the players are supposed to make, if they wanted to keep the storyline the way it happened in The Sims 2. I think. But then again, it's just a theory!
 * Probably Pleasants and Goths founded the town. I'm pretty sure that it's got something to do with Pleasants but I'm not so sure about that. Both Pleasants and Goths are almost as big families and both families appeared in the first Sims game. But Pleasant seems just like a regular family to me, so I doubt they're related to Pleasantview or its founders. Though, who knows if Pleasants founded it?
 * It's actually not so mysterious. The Landgraabs founded the town of Sunset Valley with The Goths. The Pleasants later moved to the city, and The Landgraabs moved away. Together with The Goths, The Pleasants was the dominant family in the city, and therefore became the city's name changed to Pleasantview.
