I’ll add Rarity’s side of the family to this soon, it’s on a different computer. But for now, enjoy Sweetie’s side of the Belle family. I’ll also add Rarity and Sweetie’s parents and soon, and the rest of the lines once everything is done. This will also include Cheerilee’s little family, as she is the mother to Gemstone’s half-sister, Tulip.
