Banana's new husband, Mario, has an interesting family tree. He's the grandson of Thornton and Morgana Wolff. He's got a sister named Harmony and their father is Rashawn Morris, who is the son of Monika Morris and Jared Frio. That makes him their grandson, too.
Some of you may remember that Jared Frio is the father of the baby Claire Ursine is carrying at the start of the game. That baby is usually a girl, but I've seen her have a boy once or twice. In my game, Claire's baby with Jared is named Sherry Ursine. I can see her in Mario's family tree, which means I can also see that Sherry had a half-sister named Brenna Ursine. Now, here's the twist. Brenna's father is Jared's brother, Connor Frio! That makes Sherry and Brenna half sisters and cousins!
Mario's sister, Harmony, has two children with William Bonilla, who is a second generation townie from a family who moved to town after the game started. The children are Bettina Wolff (a teen) and Aaron Wolff (an infant). They are the 4th generation of the Wolff family. The Ursine family has died off with Sherry and Brenna.
All this means that little Cinnamon has the blood of quite a few of the original townies. I think that's pretty cool.
