Shortly after her mother died in 2021, Jessica received a Facebook message from a stranger saying 'Hi, this is your sister.' It turned out her mother had secretly given up two children for adoption in the 1960s — a boy in 1964 and a girl in 1966 — before marrying. Her mother had even maintained a secret three-year relationship with the half-sister before dying, asking her to reach out after her death with the message: 'I hope they forgive me.'
