Gabriella O'hara 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 Ira O'hara, the mother of Prudence O'Mackey, the grandmother of Jason Greenman and Gabe O'Mackey, and the great grandmother of Jules O'Mackey and Daisy Greenman.
Gabriella has personality points and interests, something not every ancestral Sim has. She is completely resurrectable, even though she doesn't have a grave. Gabriella has the Knowledge aspiration, and the Scorpio zodiac sign. As far as personality, she is very active, somewhat neat, and a little bit outgoing. But she is very grouchy and rather serious.
Gabriella is one of the few ancestral Sims to die as an adult, so she died a premature death. According to her age data, she had 29 days left in the adult life stage when she died. Gabriella's facial structure is seemingly identical to the 7th Maxis face template in Create a Sim. Strangely, the "H" in her and her husband's last names are in lowercase instead of uppercase. While all the memories of pre-made playable Sims in Riverblossom Hills are positive, she has a negative memory of her husband's death.
