Question: What political office was held by two successive occupants of the same castle located in Lauderdale, Scotland?

<P0-S0> Sir Richard Maitland of Lethington and Thirlstane (1496 – 1 August 1586) was a Senator of the College of Justice, an Ordinary Lord of Session from 1561 until 1584, and notable Scottish poet. <P0-S1>  He was served heir to his father, Sir William Maitland of Lethington, East Lothian, and Thirlestane, Berwickshire, on 15 October 1515, his father being one of the casualties at the Battle of Flodden. <P0-S2>  He held the political office of Keeper of the Great Seal of Scotland and was also the Keeper of the Privy Seal of Scotland, from 1563 to 1567, and was succeeded in this post by his son Sir John Maitland, 1st Lord Maitland of Thirlestane. <SEP> <P1-S0> Raglan Castle (Welsh: "Castell Rhaglan" ) is a late medieval castle located just north of the village of Raglan in the county of Monmouthshire in south east Wales. <P1-S1>  The modern castle dates from between the 15th and early 17th-centuries, when the successive ruling families of the Herberts and the Somersets created a luxurious, fortified castle, complete with a large hexagonal keep, known as the Great Tower or the Yellow Tower of Gwent. <P1-S2>  Surrounded by parkland, water gardens and terraces, the castle was considered by contemporaries to be the equal of any other in England or Wales. <P1-S3>  During the English Civil War the castle was held on behalf of Charles I and was taken by Parliamentary forces in 1646. <P1-S4>  In the aftermath, the castle was slighted, or deliberately put beyond military use; after the restoration of Charles II, the Somersets declined to restore the castle. <P1-S5>  Raglan Castle became first a source of local building materials, then a romantic ruin, and is now a modern tourist attraction. <SEP> <P2-S0> Thirlestane Castle is a castle set in extensive parklands near Lauder in the Borders of Scotland. <P2-S1>  The site is aptly named Castle Hill, as it stands upon raised ground. <P2-S2>  However, the raised land is within Lauderdale, the valley of the Leader Water. <P2-S3>  The land has been in the ownership of the Maitland family since 1587, and Thirlestane served as the seat of the Earls of Lauderdale. <P2-S4>  The castle was substantially extended in the 1670s by the first and only Duke of Lauderdale. <P2-S5>  Further additions were made in the 19th century. <P2-S6>  The castle is now cared for by a charitable trust, and is open to the public. <SEP> <P3-S0> The Corocoro United Copper Mines, Ltd. was the largest copper mine in Bolivia, an honor previously held by Compania Corocoro de Bolivia. <P3-S1>  The corporate office was at 151 Finsbury Pavement House, London, England, while the mine office was at Coro Coro, Bolivia. <P3-S2>  It was organized August 6, 1909 under the laws of Great Britain. <P3-S3>  The lands included 515 claims in the Coro Coro district. <P3-S4>  The principal mines were the Wisk'achani, formerly owned by J. K. Child & Co., Ltd.; the Santa Rosa, formerly owned by Carreras Hermanos; and the Guallatiri, formerly owned by the Succession Noel Berthin. <P3-S5>  The mines were opened on two successive conglomerate strata of different geological horizons, and similar only in their origin and cupriferous nature. <P3-S6>  The mines are believed to have been worked by the Incas. <P3-S7>  The nearest water supply was the Rio Desaguadero, 14 miles away, down which the copper was shipped by way of Puerto de Desaguadero, and from there to Mollendo, Chile, for export to Europe.
