The first Cassuto to appear in the Dutch registers is Ephraim Cassuto. We don't know where he was born, but possibly he was a cousin of Moses Vita Cassuto, jeweller and merchant at Florence (Italy), who wrote a diary about his travels to Palestine and through Europe.For more abour the diary go to the special page about Moses Vita Cassuto's travels. Indeed I have some information Ephraim resided or was possibly born in London, according to a marriage notice in the Amsterdam registers.
Maybe he or his father travelled to London in the first half of the 18 century to represent jewell business affairs there.
Possibly Ephraim had stayed in Amsterdam to research into business possiblilties and maybe he decided to establish himself there.

Where does the name come from and who are Cassuto's of more or less reknown? Go for this to the Cassuto name page....

1. Ephraim Cassuto,
marries Hanna Savie (died 1794, Amsterdam).
Efraim gives notice at the Portuguese Isr. Synagogue of Amsterdam of the birth of:
a daughter, December 30 1747; (=Esther?)
a son, probably Juda, March 29 1751;
a daughter, February 13 1754 (=Esther?)
Birth date of Efraim is not known nor the date and place of his decease (probably outside of the Netherlands, anyway outside of Amsterdam). Though there is a marriage notice in the Sephardi registers in Amsterdam of a marriage in 1738 of an Ephraim Cassuto (witness mother Ester), born in London 1719, with Gracia de Nathan Cohen (born in 1720). Most probably this is the same Ephraim.
There is a notice of decease of Esther Cassuto, buried february 21 1771, Amsterdam.

2. Juda Cassuto, born March 29 1751, probably at Amsterdam, buried in 1823, Amsterdam.
Marries first Rachel Saqui (deceased 1777, Amsterdam) children passed away early. Marries a second time Mirjam (Marianne) Delmonte (daughter of Mordechai and of Ester Mendes Coutinho).
Three sons:
Mordechai, born April 3 1780 , Amsterdam, deceased 1808, Amsterdam, soon after birth of his son Juda. This Juda Cassuto Mzn founded the German branch: Jehuda de Mordechai Cassuto (1808-1893), moved to Hamburg and acquired a sizeable library of Spanish, Portuguese and Hebrew works in 1835 in the form of a collection started in the seventeenth century by a Portuguese Jew in Hamburg (more about
Jehuda Cassuto). Isaac Cassuto (1848-1923), Jehuda’s son, expanded the library considerably and published historical articles based on the collected material. His son Jehuda Leon Cassuto (1878-1953) had little time to devote to the contents of the library, although he lavished large sums on new acquisitions, leaving the study and description of the books to his son, Alfonso Cassuto (1910-1999).
Alfonso moved to Portugal. He sold his collection to the University of Amsterdam. His son Alvaro is director of a symphony orchestra in Lisbon.
Ephraim, born January 12 1782 te A'dam, buried July 6 1856, Amsterdam. All Dutch Cassuto's descend from him.
David, born January 31 1785, buried 1826, Amsterdam. Not married.
Mirjam, born on date not known, deceased 17 dec. Amsterdam; also is possible she was a daughter out of the first marriage of Juda.

3. Ephraim Cassuto Jzn, born January 12 1782, deceased July 6 1856, Amsterdam. He was a tailor. Marries 11 juli 1809 at Amsterdam Caatje Rebecca Lopes Quiros (birth 1784 Amsterdam, daughter of Moses and of Aletta Lindeman).
In the marriage papers the name Cassuto is spelled wrongly and Ephraim spells himself his name as Cassutto. Later, in 1961, a legal request of George Cassuto Izn to correct the name to its original spelling mode, Cassuto, was granted. His elder brother Max Izn followed this correction, and in this survey I do too. Brother Ernest didn't, so so his offspring spells Cassutto.
During the formal conclusion of the marriage at the town hall Ephraim and Rebecca acknowledge as their legal child:
Juda, born 7 march 1808. Rebbecca was not a jewess from the viewpoint of jewish law (the Halacha), because supposedly her mother wasn't. At the time of the Marriage she had converted already. At the birth of Juda Rebecca had not yet passed to judaism.
sons:
Moses, born march 7 1815- Jan. 13 1872, Amsterdam, spells his name as Casoetto, marries Hanna Henriques Coelho and is the ancestor of a small amount of Cassoetto's left, among which Jeanne Cassoetto who married Fluegelman and moved to Venezuela, daughter Jacqueline (Jacky).
David, born 1824, diamond cutter, lived in the Weesperstraat around 1850; his only child Rebecca marries in 1883 Moses Querido, son: Israel Querido.
Abraham, born 1820, Amsterdam, married to Petronella de Haas, tailor, lived in the Weesperstraat around 1850. This branch is extinct, he had one daughter, Rebecca.
Mordechay, born 1820, passed away when just married.
