Jaiden O'Mackey is one of the pre-made deceased ancestral Sims who resided during her lifetime in Riverblossom Hills, the neighborhood shipped with The Sims 2: Seasons. She was the wife of Heath, the mother of Seth, the grandmother of Jason Greenman (néO'Mackey) and Gabe, and the great-grandmother of Jules. She has personality points and interests, something not every ancestral Sim has. She is completely resurrectable, even though she doesn't have a grave.
According to Jaiden's SimDNA in SimPE, her hair was red before it turned gray. According to her age data, she had 19 days left in the elderlife stage when she died. Jaiden's facial structure is seemingly identical to the 15th Maxis face template in Create a Sim. While all the memories of pre-made playable Sims in Riverblossom Hills are positive, she has negative memories of her son's and daughter-in-law's deaths.
