Mary 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. Mary's facial structure is almost if not identical to the 25th Maxis face template in Create a Sim. Unlike several other married ancestors from Apartment Life who have memories of their spouses, she only has Mystery Sim memories. However Mary still has the memory of giving birth to Melanie. She bears a faint resemblance to Fiona Fortuna.
