Siobhan's maiden name is unknown, but she married Ben Friedman and together they had a daughter Daisy. They moved to Desertia to start a life together, but sadly Daisy died in a house fire. The fire and Daisy's death led Siobhan to have many mental issues. She divorced Ben soon after. Siobhan became scared of the kitchen, refusing to cook and living off pizza for a while, she also had two fire alarms installed. Siobhan also left Daisy's room untouched, placing Daisy's urn on the nightstand and keeping it locked for everyone apart from her. Siobhan became obsessed with having a child to replace Daisy, and soon came across a plea online. Angelo Fuchs was wanting his wife Beverly (who in reality had died years earlier) to come home so they could raise their son AJ, who was the same age as Daisy. After hearing about Beverly's description in her obituary, she realised she could easily pass herself off as Beverly. Siobhan arrived at Angelo and AJ's home claiming to be Beverly and was accepted. She grew to fall in love with Angelo, and became attached to AJ. AJ became suspicious and his suspicious were proved right when he found the real Beverly's obituary and managed to open the locked bedroom to find Daisy's ashes. Meanwhile, Siobhan convinced Angelo to have a "second wedding", so that Siobhan can be legally married to Angelo. Siobhan discovered that AJ knew her secret and locked him in Daisy's room so he couldn't disrupt the wedding. Siobhan and Angelo married, and AJ broke out and revealed the truth. Two of the wedding guests, the real Beverly's former roommate Edna and Siobhan's ex-husband Ben backed up AJ. After the wedding, Siobhan was confronted by the Angelo and AJ, and she revealed all. Angelo sympathised with her about Daisy's death, but still wanted her out because of her lying. She revealed she was pregnant with twins, and after some thought, Angelo allowed her to stay. After giving birth to twin daughters Angie and Daisy, Siobhan and Angelo divorced. Siobhan drowned in the swimming pool soon after, leaving Angelo to once again be a single father.
