Will made by António Velez da Silveira and his wife Guiomar Ferreira in which they ordered, among other dispositions, the foundation of an entail with a perpetual obligation of 70 masses celebrated every year in the chapel they would build in Arronches, where a lamp would be perpetually lit. They named their nephew António Velez as first administrator and after his death, the succession should continue, preferably, on the eldest male heir, but if he had no male sons, then the administration would be handled to the closest male relative of the institutor, in ways that the females would only assume the administration in case of complete absence of male heirs or relatives. All administrators would bare the surname "Velez da Silveira" and would be obliged to sign a document stating that they would annex half of their own reserved portions to this entail by the time of their deaths. Besides, the administrators should always keep a key of the chapel.
