By 1232, there was probably a Jewish community in Ireland, as a grant of 28 July 1232 by King Henry III to Peter de Rivel gives him the office of Treasurer and Chancellor of the Irish Exchequer, the king's ports and coast, and also "the custody of the King's Judaism in Ireland". This grant contains the additional instruction that "all Jews in Ireland shall be intentive and respondent to Peter as their keeper in all things touching the king". The Jews of this period probably resided in or near Dublin. In the Dublin White Book of 1241, there is a grant of land containing various prohibitions against its sale or disposition by the grantee. Part of the prohibition reads "vel in Judaismo ponere" (prohibiting it from being sold to Jews). The last mention of Jews in the "Calendar of Documents Relating to Ireland" appears about 1286. After the 1290 Edict of Expulsion of Jews from England, Jews living in the English Pale around Dublin may have had to leave English jurisdiction. It would not have been difficult for Jews to defy the 1290 Edict by moving beyond English settlement into the Gaelic Irish areas that England did not control. It is thought the Danes of Oxmantown requested the assistance of the Danes of Wexford to ensure the Jewish community could migrate through Anglo-Norman controlled land to establish a settlement in Gaelic O’Donovan territory.
