Installed in Buenos Aires he participated in the economic  activities of the Río de la Plata as a naval merchant. He was married in Buenos Aires, to Ana de la Trinidad Martínez, daughter of Juan Gil de Freytas and María Martínez, possibly belonging to families established in the City during the second foundation of Buenos Aires by Juan de Garay. His wife's family was linked to Manuel de Frías, a distinguished military man born in Asunción, who held various political posts in the Río de la Plata, including that of lieutenant governor of Buenos Aires.
