Lucia Riley

Lucia Riley (née Kupyi) is the wife of Seamus Riley, the mother of Timothy Riley, and the grandmother of Sally Riley. Not much is known about her since she is deceased before the start of The Sims 2.

From her son's memories, it shows she raised him alone, after her husband died while Timothy was a Toddler. She is meant to be deceased, but her son has no memory of her dying, so it is assumed he was not informed or wasn't present of her death.
