A London Gomes Da Costa mystery. I have been looking through the annual accounts of Bevis Marks for references to GDC family member before 1727, the year that Abraham and Abigail GDC first turn up. This is the year Abraham was circumcised, on the same day as his brother Isaac. Abraham and Abigail, and Isaac and Ribca remarry on the same day the following year, in 1728However, the accounts show that between 1700 (5460) and 1706 (5466), an Isaac Gomes Da Costa was the recipient of aid in kind of coal and bread, as well as payments at Sucoth and Pesah in two of those years. The picture above is from the Reparticao do Mazoth list for 5462 (p.198). Who is this Isaac? He is not Abraham's brother Isaac, as that Isaac was only circumcised in 1727, and was therefore not Jewish before that (we also know that he was a Vindos de Portugal, who arrived as a refugee in about 1727.)This earlier Isaac disappears from the accounts in 1706, suggesting that maybe he died. Yet, there does not seem to be a burial record for him in the Velho (old) cemetery, which was in use at the time. Maybe the Velho records are incomplete, or maybe he moved away from England.There is another early GDC, Sarah, who appears in the accounts from 1706 onwards as the recipient of a very wide range of charity payments. There is a burial record for her in the Velho on 14 July 1726. Who is Sarah? Could she be the earlier Isaac's widow, as she starts receiving charity in the same year that Isaac stops? There is also a third early GDC, Judica de Isaac, who in 1724 marries an Abraham Carrazco. This is clearly not the daughter of the Isaac who who was the brother of our Abraham. She is either the daughter of the earlier Isaac or (less likely given the large gap between 1707 and 1724) his widow. How, if at all, are they related to Abraham and Abigail? All three disappear from the records before Abraham and Abigail arrive on the scene in 1727. Has anyone in the group come across these names, or have a theory?
