Entail foundation deed by which Duarte Correia de Sousa, escrivão da Câmara do Rei e dos Despachos e Negócios das comarcas de Alentejo e Algarve, son of Pedro Vaz Correia and D. Inês de Sousa and stepson of Salvador Correia de Sá, establishes an entail with the properties he inherited from his relatives: a farmstead in Alvalade, houses in Lisboa and lands in Chamusca. He designates his cousin, Jerónimo de Castro, son of his aunt D. Luísa de Lacerda, as first administrator of his entail, and his descendants afterwards. If he has no successors, the entail shall pass to his other cousins Rui Correia Lucas, D. Catarina Salema, or António Teixeira Telo. The administrator of his entail shall also administer the chapel he established in the sacristy of the monastery of Santíssima Trindade, where he wishes to be buried, founded in 1615-12-29. This chapel has the obligation of a daily mass, two weekly masses and other annual masses.
