Mrs. Murphy (née Ms. Hammond) is the British daughter of John Hammond and ex-wife of Mr. Murphy. She was in the process of divorcing her husband at the time of the Isla Nublar Incident. She is mentioned and not seen in both incarnations of Jurassic Park.
- ↑ Lex was born in 1980, so Mrs Murphy had to be at least 18 to have legally married her husband - which she has, as they're getting divorced - plus a nine month pregnancy to have Lex. This places her at, at a minimum, aged 19 when Lex was born - meaning the latest date she can be born is 1961.
- ↑ John Hammond is Scottish born, so his daughter is British by blood, but married an American; whether she is Scottish like her father is unknown; she could be born anywhere in the British Isles.
