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.
