Archive of the Marquises of Rocaverde
This is a family archive that came into the possession of the Bascongada, on the death of the childless Mr. Leonardo de Moyua y Alzaga (1920), who was better known as Leo de Silka, and which was ceded by his widow along with his piano and personal portrait. It primarily comprises private documentation, which is of great interest to Gipuzkoa because of the importance of the surnames of the following families: Ayerdi, Moyua, Tompes, Amézqueta, Lopeola, Alzaga, Emparán, Adarraga and Mazarredo. The archive also contains public documents, resulting from some members of the family who held public offices.
