Isaac Rubinstein

Isaac Rubinstein was husband to Annabel Rubinstein, father of one daughter as well as the guardian of Nicola Rubinstein, who he raised as his own.

Originally from Liverpool, Isaac was married to Annabel Rubinstein and the pair already had one daughter when Annabel fell pregnant again, this time not with Isaac's baby but with Pat Phelan's. After Isaac learnt the truth of the parentage, Annabel told him that she'd been a victim of rape at the hands of Phelan and the pair fled the city in 1990 after Nicola's birth so that she would never learn the truth.

Issac and Annabel later died in a car crash and Nicola discovered the truth after being investigated by Pat. Upon growing close to her real father Nicola was given two different versions of events as to why her mother fled Liverpool. The first was from Annabel's close friend Lydia Hartman who claimed Pat had raped Annabel and in shame her and Issac departed the city - while Pat's version of events claimed that Annabel had been unfaithful, having a full-blown affair with Pat, but when Issac found out she chose him and claimed rape. After then discovering that Pat raped another woman, Anna Windass, Nicola chose to believe Lydia and wanted nothing more to do with her father.

In May 2018, Nicola gave birth to a son and named him Zac Rubinstein after her father.
