Isaac Epstein married Dinah Hyman in Manchester in 1900. In 1901, Isaac and Dinah were living at 80 Walton Road, Liverpool, with Isaac's sister Rachael Epstein, above the furniture dealership that he founded. Dinah and Isaac's third child was Harry Epstein, Brian Epstein's father. Eventually the family moved to a larger home in the Anfield area of Liverpool at 27 Anfield Road. After Harry and his brother Leslie had joined the family firm, Isaac Epstein founded. Epstein and Sons then enlarged the furniture business by taking over adjacent shops at 62/72 Walton Road to sell a range of other goods, such as musical instruments and household appliances. They called the expanding business NEMS (North End Music Stores), which offered lenient credit terms, and from which Paul McCartney's father once bought a piano. Epstein's mother Malka (nicknamed "Queenie" by her family, as Malka means "queen" in Hebrew) was also involved in the Hyman furniture business, which also owned the Sheffield Veneering Company.
