Documents produced by the entail.

Will by which Álvaro de Valadares, son of João de Valadares and Ana de Azevedo, founded an entail, incorporating the farm of Póvoa and his third with the obligation to celebrate masses wherever he would be buried. He designated his wife Antónia Carneiro to be its first administrator and, after her death, his eldest son João Valadares Carneiro. If he did not have heirs, this entail should be succeeded by his second son Pantaleão and his heirs.
