The Hans M. Koch House, also known as the Brickyard Residence, is a historic building located in the extreme southern portion of Kimballton, Iowa, United States.
 Its significance is derived from its association with the Danish immigrant settlement of the area, and the skilled Danish craftsman who lived and worked here.
 The house was the work of its owner, Hans Koch, who was also the manager of the Crystals Springs brickyard nearby.
 He was a native of Slesvig, Denmark and immigrated to the United States twice.
 He first settled in Michigan in 1893 before returning to Denmark four years later.
 He immigrated a second time in 1908 settling in Kimballton.
 He worked as a brickmaker everywhere he lived.
 Built in 1908, the 1½-story brick structure is a gabled double-pile house type, which was common in the Danish settlement area of Shelby and Audubon counties in the early 20th century.
 It may also be an example of a Danish house form.
 It was listed on the National Register of Historic Places in 1991.
The Danish House of Knýtlinga (English: "House of Cnut's Descendants") was a ruling royal house in Middle Age Scandinavia and England.

 It has also been called the House of Canute, the House of Denmark, the House of Gorm, or the Jelling Dynasty.
The Duchy of Holstein (German: "Herzogtum Holstein" , Danish: "Hertugdømmet Holsten" ) was the northernmost state of the Holy Roman Empire, located in the present German state of Schleswig-Holstein.
 It was established when King Christian I of Denmark had his County of Holstein-Rendsburg elevated to a duchy by Emperor Frederick III in 1474.
 Holstein was ruled jointly with the Duchy of Schleswig by members of the Danish House of Oldenburg for its entire existence.
Lord Banquo , the Thane of Lochaber, is a character in William Shakespeare's 1606 play "Macbeth".
 In the play, he is at first an ally to Macbeth (both are generals in the King's army) and they are together when they meet the Three Witches.
 After prophesying that Macbeth will become king, the witches tell Banquo that he will not be king himself, but that his descendants will be.
 Later, Macbeth in his lust for power sees Banquo as a threat and has him murdered; Banquo's son, Fleance, escapes.
 Banquo's ghost returns in a later scene, causing Macbeth to react with alarm during a public feast.

Svein Knutsson (Old Norse: "Sveinn Knútsson") c. 1016–1035, was the son of Cnut the Great, king of Denmark, Norway, and England, and his first wife Ælfgifu of Northampton, a Mercian noblewoman.
 In 1017 Cnut married Emma of Normandy, but there is no evidence that Ælfgifu was repudiated, and in 1030 Cnut sent her and Svein as regents to rule Norway.
 However, their rule was considered oppressive by the Norwegians, and they were expelled in 1034.
 They imposed new taxes and harsh laws that made them unpopular.
 In William Shakespeare's "Macbeth", there is a character called "Sweno, the Norways' king" based on Svein.
