Before 1147, there were several settlements between Leiria and Lisbon. Where Yaish lived, in Lisbon, was a large nucleus of Jews, with synagogues and infrastructure to support Jewish life.

(A dos Negros); this donation refers to the taking of Óbidos (near Aldeia dos Negros) in 1148. In the Register of Population of the Kingdom, made by King João III of Portugal, in 1527, the Village of Blacks had about 90 inhabitants).After claiming his land, Yaish Flourished and died about 1150. In honor of his reward, and in reference to the Moors Yaish and his descents bore the additional cognomen, "Negro".

The Synagogue of Óbidos is located in the old Jewish Quarter and dates to the 7th-century C.E where a Jewish community was re-established after the Visigoths seized the village in the 5th century. Óbidos was taken in 1148, by the Jewish vizier, Yaish ibn Yahya; in return for its liberation King Afonso Henriques I rewarded Yaish ibn Yahya with a nearby town and anointed him "Lord of Unhos, Frielas and Aldeia dos Negros".
