Castles in Great Britain and Ireland: Castles have played an important military, economic and social role in Great Britain and Ireland since their introduction following the Norman invasion of England in 1066.  Although a small number of castles had been built in England in the 1050s, the Normans began to build motte and bailey and ringworks castles in large numbers to control their newly occupied territories in England and the Welsh Marches.  During the 12th century the Normans began to build more castles in stone – with characteristic square keeps – that played both military and political roles.  Royal castles were used to control key towns and the economically important forests, while baronial castles were used by the Norman lords to control their widespread estates.  David I invited Anglo-Norman lords into Scotland in the early 12th century to help him colonise and control areas of his kingdom such as Galloway; the new lords brought castle technologies with them and wooden castles began to be established over the south of the kingdom.  Following the Norman invasion of Ireland in the 1170s, under Henry II, castles were established there too.

Let's Build a World Together (song): "Let's Build a World Together" is a love song by George Jones and Tammy Wynette.  It was the married couple's fourth single together on Epic Records and became the title track of their fourth LP in 1973.  Although the song expressed the promise of new love, 1973 would be the beginning of the end as far as their marriage was concerned, with Wynette filing for divorce for the first time in August of that year.  Their tumultuous personal life, which often made the gossip papers, coupled with their flawless vocal harmonies on love songs like "Let's Build a World Together," mesmerized their fans.  Indeed, the more their lives deteriorated, the bigger hits the couple would have, especially after their 1975 divorce.  However, "Let's Build a World Together" was not a hit, only making it to #32 on the "Billboard" singles chart.  Interestingly, co-writer George Richey would become Wynette's fifth husband.

George Parsons (shipbuilder): George Parsons was born in Poole, the son of George Parsons, and was baptised at St James, Poole, 21 September 1729.  His father moved to Portsmouth to take up a position as a shipwright in the Royal Dockyard in 1740.  George junior began as a Quarter Boy entering 18 June 1744.  He continued in the Royal Dockyard until, as a 2nd shipwright he was discharged 6 April 1763.  His move to Bursledon therefore probably occurred later that year and certainly by 1764.  His first employer there was a shipowner, Thomas Cooper, and a few years later, Philemon Ewer, a descendant of the pre-eminent local shipbuilder of the previous generation.  He almost certainly moved into his own yard by 1774 at Bursledon Point on the Hamble, though the advertisement in 1776 for 'a good burthensome well built Sloop, about 30 tons, just finished' suggested this might have been built in partnership with Ewer.  By late 1778 he was ready to build on his own account when a Navy Board letter of 19 December refers to an offer from him to build 'a Ship of 32 guns'.

Light Railways Act 1896: The Light Railways Act 1896 (59 & 60 Vict.  c.48) was an Act of the Parliament of the United Kingdom of Great Britain and Ireland (as it then was).  Before the Act each new railway line built in the country required a specific Act of Parliament to be obtained by the company that wished to construct it, which greatly added to the cost and time it took to construct new railways.  The economic downturn of the 1880s had hit agriculture and rural communities in the United Kingdom especially hard and the government wished to facilitate the construction of railways in rural areas, especially to facilitate the transport of goods.  The 1896 Act defined a class of railways which did not require specific legislation to construct – companies could simply plan a line under the auspices of the new Act, and, having obtained a Light Railway Order, build and operate it.  By reducing the legal costs and allowing new railways to be built quickly the government hoped to encourage companies to build the new 'light railways' in areas of low population and industry that were previously of little interest to them.

York, Upper Canada: The Town of York was the second capital of the district of Upper Canada and the predecessor to Toronto (1834).  It was established in 1793 by Lieutenant-Governor John Graves Simcoe as a "temporary" location for the capital of Upper Canada, while he made plans to build a capital near today's London, Ontario.  Simcoe renamed the location York after Prince Frederick, Duke of York and Albany, George III's second son.  Simcoe gave up his plan to build a capital at London, and York became the permanent capital of Upper Canada on February 1, 1796.  That year Simcoe returned to Britain and was temporarily replaced by Peter Russell.
