However, the three most prominent of the seven brothers pursued high profile careers as civil servants in the new Bourbon regime established in Spain after the end of the War of Succession. Fernando Verdes-Montenegro (1682-1741) entered the service of the Count-Duke of Benavente, territorial lord of Puebla de Sanabria, shortly after his father's death. A few years later, in 1716, he provided proof of nobility to join the Order of Calatrava. The same year he entered the royal service at His Majesty's "Contaduría Mayor" (a financial control body) and steadily climbed the ranks until being appointed Secretary of Finance ("Secretario del Despacho Universal de Hacienda") in 1724. Four years later, Fernando joined the powerful Royal Council of the Indies and in 1740 he was again appointed Secretary of Finance to king Philip V during his second reign. His younger brother Juan Diego Verdes-Montenegro (1690-1763) followed his steps. He also entered the service of the Count-Duke of Benavente (1716) and went through the exacting admission process to a Military Order, donning the habit of the Order of Santiago in 1730. But in contrast to Fernando, who settled in Madrid, Juan Diego moved to Valencia, where he was appointed Treasurer of the Viceroyalty (customarily named Kingdom of Valencia) and of its Army and also a member of His Majesty's Council at the "Contaduría Mayor". Finally, Miguel Verdes-Montenegro (1697-1767) was a scholar at Salamanca (1719-1730), judge at the Royal Chancellery of Valladolid (1738), Knight of the Order of Santiago (1740) and Dean of the Council of the Spanish military orders in 1767
