Here are a few townie offspring living in my current town.
I'm quite new to the game so I don't know if the story progression is totally random or do these same sims tend to pop up. I've had a few games in Sunset Valley but never really paid attention to townie kids before this one.
Let's start with Arlo Bunch's son... His mother is Sandi French. Not THAT bad looking considering his father...? He had an annoying personality and rather odd looks so my sim daughter didn't choose him after all.
Next, my favorite! This sim was a best friend of my sim's first daughter, and she was a little odd looking even as a child (with that haircolor, a short hairstyle and a bit too much weight). She is Lea Alto, daughter of Holly Alto and Malcolm Landgraab.
I don't know about this girl. I kind of like her, even though she has a somehow simian look... or is it just me? She's the daughter of Tamara Donner and Xander Clavell.
And finally the guy who became a spouse to one of my current family's daughters. He is the son of Connor Frio and Rafaela Hart - he had twin girls with my sim and one of them looks quite a bit like Connor.
