thanks for the question! you didn’t specify which OC so i’m going to go ahead and do this for the two heirs of each generation!
3. What is the meaning behind their name? Do they have any nicknames?
Well according to babynamewizard, Nathalie is a French variant of the name Natalie, which means “Christmas”... which is ironic since her son is the Christmas baby not herself. Speaking from a creator standpoint, Nathalie was literally just one of the random generated names in CAS and I just thought it fit.
She doesn’t have many nicknames, frankly bc she only had like 1 friend outside of the household. She’s okay with Nat and that’s basically it.
Harrison’s name means “Son of Harris/Harry” and was originally used as a surname. To be completely honest, I just gave him the name Harrison bc of Harrison Ford. So in story universe he’s named after I guess the Sims version of Harrison Ford.
As a nickname, his family calls him Harry. If you’re not family and try to refer to him as that, he’s not going to answer. His friends and co-workers mainly refer to him by his last name, DeVille, unless things are really serious.
