Will of João Domingues, citizen of Porto, and his wife Maria Eanes da Rua. They both reserved their "terças" to found a chapel, incorporating the "Paço de Valadares" and the "Casal de Castanheiro", located in the "Julgado de Gaia". Part of the income from these estates would support the celebration of perpetual masses in the convent of S. Francisco do Porto and in the chapel they also established in the church of S. Salvador de Valadares, dedicated to S. António. The first administrator of the entail would be their son, Francisco da Rua, to be followed by the first-born sons or daughters, in the absence of male heirs. In the event of the line being broken, the institutions would call upon their closest relatives to succeed them. Alternatively, if there were no relatives, the Misericórdia of Porto would take possession of the estates and administer the chapel.

Documents produced by the entail.

Donation deed by João Eanes, mercador, and his wife Maria Eanes da Rua, to the monastery of S. Francisco do Porto. For the salvation of their souls, the couple decided to leave the rents of properties located in Porto to the Convent of S. Francisco do Porto, where they would choose their burial place and where perpetual masses would be celebrated. The monastery accepted the dues, the fees of which would be paid by the heir of João Eanes and Maria Eanes, who would act as administrator, followed by their descendants, by appointment or, if the last owner did not name an heir, by preference of the male over the female.

Acceptance deed by Maria Eanes da Rua, declaring in the presence of the local judge that she freely participated in the donation made by her husband to the monastery of São Francisco do Porto.
