I as watching the eppie when Olivia's mom died yesterday and it got me thinking what ever happened to her dad??

As a child of rape, she never met her father. In season 8, she tests her DNA out of curiosity ans perhaps the hope of finding her father অথবা a sibling. She finds a man named Simon Marsden, her half brother. She tracks him down and tries to contact her father, who died years earlier. She does however talk to her father's wife, who suffers from Alzheimer's Disease.

Olivia never met her dad. Her mom was raped andthe man who raped her mom is her dad. Her mom died and then Olivia met her brother during season 8. She finds brother, Simon Masden and she finds out their dad died.
