He married Edith Constance Newton (1880–1951), whose family had changed its name from its original Nathan, at the West London Synagogue on Tuesday 26 July 1898.
By the mid-1880s, Goldstein had founded the Edwards' Harlene Co., manufacturers of hair products, initially of 5 New Oxford Street and by late 1891 of 95 and 96 High Holborn, London.
