Context paragraphs:
Ranulf de Blondeville, 6th Earl of Chester: Ranulf de Blondeville, 6th Earl of Chester and 1st Earl of Lincoln (1170–1232), known in some references as the 4th Earl of Chester (in the second lineage of the title after the original family line was broken after the 2nd Earl), was one of the "old school" of Anglo-Norman barons whose loyalty to the Angevin dynasty was consistent but contingent on the receipt of lucrative favours.  He was described as "almost the last relic of the great feudal aristocracy of the Conquest".

Milntown Castle: Milntown Castle was an early 16th-century castle which was situated near Milton, in Easter Ross, in the Scottish Highlands.  It was built by the Munro of Milntown family, a cadet branch of the Clan Munro.  In 1656, the castle and estate was sold to George Mackenzie, 1st Earl of Cromartie also known as George MacKenzie of Tarbet.  He renamed the estate New Tarbat after Tarbat Castle (now more commonly known as Ballone Castle), the family's original seat near Portmahomack.  Mackenzie had the Milntown Castle pulled down and only part of the basement survives.  He then replaced the castle with a new mansion built nearby.  When the new mansion was built, the old Milntown Castle was remodelled as part of the garden.  That mansion was itself demolished and in 1787 was replaced with a Georgian house (now known as Tarbat House) by his descendant John Mackenzie, Lord MacLeod.

Castle Acre Castle and town walls: Castle Acre Castle and town walls are a set of ruined medieval defences built in the village of Castle Acre, Norfolk.  The castle was built soon after the Norman Conquest by William de Warenne, the Earl of Surrey, at the intersection of the River Nar and the Peddars Way.  William constructed a motte-and-bailey castle during the 1070s, protected by large earthwork ramparts, with a large country house in the centre of the motte.  Soon after, a small community of Cluniac monks were given the castle's chapel in the outer bailey; under William, the second earl, the order was given land and estates to establish Castle Acre Priory alongside the castle.  A deer park was created nearby for hunting.

Northburgh Castle: Northburgh Castle, also known as Green Castle, is a ruined 14th-century castle near Greencastle, County Donegal, Ireland.  It was built in 1305 by Richard Óg de Burgh, 2nd Earl of Ulster.  Northburgh Castle was sited to control Lough Foyle, and was captured by Edward Bruce in 1316.  Walter Liath de Burgh was imprisoned in 1328 at the castle by his cousin William Donn de Burgh, 3rd Earl of Ulster, and died of starvation in February 1332.  William’s sister was found dead beneath the battlements.  After William's death, the castle became a stronghold of the O'Doherty family.  Northburgh Castle suffered considerable damage by cannon fire and eventually was left in ruins after the 17th century.

Loch Leven Castle: Loch Leven Castle is a ruined castle on an island in Loch Leven, in the Perth and Kinross local authority area of Scotland.  Possibly built around 1300, the castle was the location of military action during the Wars of Scottish Independence (1296–1357).  In the latter part of the 14th century, the castle was granted by his uncle to William Douglas, 1st Earl of Douglas, and remained in Douglas' hands for the next 300 years.  Mary, Queen of Scots was imprisoned here in 1567–1568, and forced to abdicate as queen, before escaping with the help of her gaoler's family.  In 1588, the Queen's gaoler inherited the title Earl of Morton, and moved away from the castle.  It was bought, in 1675, by Sir William Bruce, who used the castle as a focal point in his garden; it was never again used as a residence.

Earl of Warwick: Earl of Warwick ( ) is a title that has been created four times in English history and is one of the most prestigious titles in the peerages of the United Kingdom.  The first creation came in 1088, and was held by the Beaumont, and later by the Beauchamp families.  The 14th Earl was created Duke of Warwick in 1445, a title which became extinct on his early death the following year.  The best-known Earl of this creation was the 16th Earl, Richard Neville, who was involved in the deposition of two kings, a fact which later earned him his epithet "Warwick the Kingmaker".  This creation became extinct on the death of the 17th Earl in 1499.  The title was revived in 1547 for the powerful statesman John Dudley, 1st Viscount Lisle, who was later made Duke of Northumberland.  The earldom was passed on during his lifetime to his eldest son, John, but both father and son were attainted in 1554.  The title was recreated or restored in 1561 in favour of Ambrose, younger son of the Duke of Northumberland.  However, Ambrose was childless and the earldom became extinct on his death in 1590.  It was created for a third time in 1618 for Robert Rich, 3rd Baron Rich, in spite of the fact that the Rich family were not in possession of Warwick Castle.  From 1673 the Earls also held the title Earl of Holland.  All the titles became extinct on the death of the 8th Earl in 1759.  The earldom was revived the same year in favour of Francis Greville, 1st Earl Brooke.  The Greville family were in possession of Warwick Castle and the title and castle were thereby re-united for the first time in over a century.  The 1759 creation is extant and currently held by Guy Greville, 9th Earl of Warwick.  However, Warwick Castle was sold by the family in 1978, and they currently live in Australia.

James Butler, 3rd Earl of Ormond: James Butler, 3rd Earl of Ormond (c. 1359 – 7 September 1405), was a noble in the Peerage of Ireland.  He acceded to the title in 1382 and built Gowran Castle three years later in 1385 close to the centre of Gowran making it his usual residence, whence his common epithet, "The Earl of Gowran".  James died in Gowran Castle in 1405 and is buried in St. Mary's Collegiate Church Gowran together with his father James Butler, 2nd Earl of Ormond, his grandfather James Butler, 1st Earl of Ormond and his great great grandfather Edmund Butler, Earl of Carrick and 6th Chief Butler of Ireland.  James the 2nd Earl was usually called The Noble Earl, being a great-grandson, through his mother, of King Edward I of England.

Beeston Castle: Beeston Castle is a former Royal castle in Beeston, Cheshire, England (grid reference [ SJ537593] ), perched on a rocky sandstone crag 350 ft above the Cheshire Plain.  It was built in the 1220s by Ranulf de Blondeville, 6th Earl of Chester, (1170–1232), on his return from the Crusades.  In 1237, Henry III took over the ownership of Beeston, and it was kept in good repair until the 16th century, when it was considered to be of no further military use, although it was pressed into service again in 1643, during the English Civil War.  The castle was slighted (partly demolished) in 1646, in accordance with Cromwell's destruction order, to prevent its further use as a stronghold.
