Albert Behar (a.k.a. Albert Isaiah Mercado) was a British subject born in Istanbul. On April 27, 1914, Albert’s sister Victoria Ner Mercado, née Behar, and her husband Maurice Mercado adopted Albert’s child, a boy named Robert Isaiah Behar, born in Brussels on November 17, 1910. The Home Office decided not to automatically naturalize Robert under his adoptive father Albert, who was naturalized in 1927, after a thirteen-year legal ordeal.

Albert Behar’s pseudonym is strong evidence (together with parallel testimony from the records of Isaac Behar/Albert Salisse of Glasgow) that many Sephardi Jews had two sets of names, one marking association with the father, the other with the mother.
