Saint Margaret of Scotland in the context of "Matilda of Scotland"

David I or Dauíd mac Maíl Choluim (Modern Gaelic: Daibhidh I mac [Mhaoil] Chaluim; c. 1084 – 24 May 1153) was a 12th century ruler and saint who was Prince of the Cumbrians from 1113 to 1124 and King of Scotland from 1124 to 1153. The youngest son of King Malcolm III and Queen Margaret, David spent most of his childhood in Scotland but was exiled to England temporarily in 1093. Perhaps after 1100, he became a dependent at the court of King Henry I of England, by whom he was influenced.

When David's brother Alexander I died in 1124, David chose, with the backing of Henry I, to take the Kingdom of Alba (Scotland) for himself. He was forced to engage in warfare against his rival and nephew, Máel Coluim mac Alaxandair. Subduing the latter seems to have taken David ten years, a struggle that involved the destruction of Óengus, Mormaer of Moray. David's victory allowed the expansion of control over more distant regions, theoretically part of his Kingdom. After the death of his former patron Henry I, David supported the claims of Henry's daughter and his own niece, Empress Matilda, to the throne of England. In the process, he came into conflict with King Stephen and was able to expand his power in northern England, despite his defeat at the Battle of the Standard in 1138. David I is a saint of the Catholic Church, with his feast day celebrated on 24 May.

Malcolm III (Middle Irish: Máel Coluim mac Donnchada; Scottish Gaelic: Maol Chaluim mac Dhonnchaidh; c. 1031–13 November 1093) was King of Alba from 1058 to 1093. He was later nicknamed "Canmore" (Scottish Gaelic: ceann mòr, lit. 'big head', understood as "great chief"). Malcolm's long reign of 35 years preceded the beginning of the Scoto-Norman age. Henry I of England and Eustace III, Count of Boulogne were his sons-in-law, making him the maternal grandfather of Empress Matilda, William Adelin and Matilda I, Countess of Boulogne. All three of them were prominent in English politics during the 12th century.

Malcolm's kingdom did not extend over the full territory of modern Scotland: many of the islands and the land north of the River Oykel were Scandinavian, and south of the Firth of Forth there were numerous independent or semi-independent realms, including the kingdom of Strathclyde and Bamburgh, and it is not certain what if any power the Scots exerted there on Malcolm's accession. Throughout his reign, Malcolm III led at least five invasions into English territory. One of Malcolm's primary achievements was to secure the position of the lineage that ruled Scotland until the late thirteenth century, although his role as founder of a dynasty has more to do with the propaganda of his descendants than with history. He appears as a major character in William Shakespeare's Macbeth, while his second wife, Margaret, was canonised as a saint in the thirteenth century.

South Queensferry, also known simply as Queensferry or The Ferry, is a town to the west of Edinburgh, Scotland. Traditionally a royal burgh of West Lothian, it is now administered by the City of Edinburgh Council. It lies ten miles to the north-west of Edinburgh city centre, on the southern shore of the Firth of Forth, between the Forth Rail Bridge, the Forth Road Bridge and the Queensferry Crossing.

The prefix South distinguishes the town from North Queensferry, on the opposite shore of the Forth. Both towns derive their name from the ferry service established by Queen Margaret in the 11th century, which continued to operate at the town until 1964, when the Road Bridge was opened.

North Queensferry is a historic coastal village in Fife, Scotland, situated on the Firth of Forth, 9 mi (14 km) from Edinburgh city centre. Located on the North Queensferry Peninsula, it is the southernmost settlement in Fife.

The town derives its name from the ferry service established by Queen Margaret in the 11th century; the prefix North serves to distinguish it from South Queensferry, on the opposite shore of the Forth. The Forth Rail Bridge (1890), the Forth Road Bridge (1964) and the Queensferry Crossing (2017) all meet the Fife coast at North Queensferry.

Cristina, daughter of Edward the Exile and Agatha, was the sister of Edgar Ætheling and Saint Margaret of Scotland, born in the 1040s. Cristina's nieces Edith and Mary were sent to Romsey Abbey, near Southampton, in 1086 when she was abbess.

Edgar or Étgar mac Maíl Choluim (Modern Gaelic: Eagar mac Mhaoil Chaluim), nicknamed Probus, "the Valiant" (c. 1074 – 8 January 1107), was King of Alba (Scotland) from 1097 to 1107. He was the fourth son of Malcolm III and Margaret of Wessex but the first to be considered eligible for the throne after the death of his father.
