Question: What country of origin does Eystein Orre and Battle of Stamford Bridge have in common?

Context paragraphs:
Lillie Bridge Grounds: The Lillie Bridge Grounds was a sports ground on the Fulham side of West Brompton, London.  It opened in 1866, coinciding with the opening of West Brompton station.  It was named after the local landowner, Sir John Scott Lillie (1790–1868) and the Lillie bridge over the West London Line, that links Old Brompton Road with Lillie Road.  The grounds were adjacent to the railway on the south side of Lillie Road.  Although geographically near to present day Stamford Bridge, there was never direct access, there being the 13 acre now defunct Western Hospital site between the two.  The ground was the scene in its day of many sports including athletics, boxing, cricket, cycling and football, and hosted the FA Cup Final in 1873.  It closed in 1888 following a riot reported in "The Times".

Eystein I of Norway: Eystein Magnusson (Old Norse: "Eysteinn Magnússon", Norwegian: "Øystein Magnusson"; c. 1088 – 29 August 1123) was King of Norway (as Eystein I) from 1103 to 1123 together with his brothers Sigurd the Crusader and Olaf Magnusson, although since Olaf died before adulthood, only Eystein and Sigurd were effective rulers of the country.

Battle of Stamford Bridge: The Battle of Stamford Bridge took place at the village of Stamford Bridge, East Riding of Yorkshire, in England on 25 September 1066, between an English army under King Harold Godwinson and an invading Norwegian force led by King Harald Hardrada and the English king's brother Tostig Godwinson.  After a bloody battle, both Hardrada and Tostig along with most of the Norwegians were killed.  Although Harold Godwinson repelled the Norwegian invaders, his army was defeated by the Normans at Hastings less than three weeks later.  The battle has traditionally been presented as symbolising the end of the Viking Age, although major Scandinavian campaigns in Britain and Ireland occurred in the following decades, such as those of King Sweyn Estrithson of Denmark in 1069–1070 and King Magnus Barefoot of Norway in 1098 and 1102–1103.

Eystein Orre: Eystein Orre (Old Norse: "Eystein Orri"; died 25 September 1066) was a Norwegian noble who was killed at the Battle of Stamford Bridge in 1066.

Stamford Bridge (Cedar Butte, South Dakota): The Stamford Bridge, also known as Bridge No. 48-102-010, is a historic bridge in rural Mellette County, South Dakota, southeast of Stamford.  Built in 1930, it is a three-span Bedstead Pony Truss bridge, carrying a local road over the White River, off County Road Ch 1.  Each span measures 80 ft in length, and the rest on two concrete piers and two concrete abutments with wing walls.  The deck consists of steel I-beams, with wooden stringers topped by steel plates.  The bridge is the longest Bedstead truss bridge in the state, and one of a modest number of surviving bridges built using this type of truss.

Martin Knight (author): Martin Knight is a British author born in Epsom in Surrey in 1957 mainly associated with working class culture and football literature.  In 1999 "Hoolifan" and "The Naughty Nineties" were released; both books dealing with the subject, culture and history of football hooliganism.  Knight was co-author with Martin King whose hooligan memoirs form the core of the books.  Irvine Welsh provided the introduction to the latter book.  As partners, Knight and King produced "On the Cobbles" the story of Jimmy Stockin a renowned gypsy prize fighter, "Ossie – King of The Bridge" – the autobiography of Chelsea footballing legend Peter Osgood and "Grass" covering the exploits of major drug smuggler and Howard Marks' cohort Phil Sparrowhawk.  In September 2010 a copy of "Ossie – King of the Bridge" (among other items) was buried beneath the new statue of Peter Osgood unveiled at Stamford Bridge.

Ancestry of the Godwins: Very little is known for certain of the ancestry of the Godwins, the family of the last Anglo-Saxon King of England, Harold II.  When King Edward the Confessor died in January 1066 his closest relative was his great-nephew, Edgar the Ætheling, but he was young and lacked powerful supporters.  Harold was the head of the most powerful family in England and Edward's brother-in-law, and he became king.  In September 1066 Harold defeated and killed King Harald Hardrada of Norway at the Battle of Stamford Bridge, and Harold was himself defeated and killed the following month by William the Conqueror at the Battle of Hastings.
