Title: Regnal number
Content:  While reigning monarchs use ordinals, ordinals are not used for royal female consorts. So whereas King George V used an ordinal to distinguish him from other kings in the United Kingdoms called George, his wife, Queen Mary, had no ordinal. The lack of an ordinal in the case of royal consorts complicates the recording of history, as there may be a number of consorts over time with the same name with no way to distinguish between them. For that reason, royal consorts are sometimes after their deaths recorded in history books and encyclopaedias through the use of their pre-marital name or, if from royalty or sovereign nobility, the name of the dynasty or the country. For example, Henry VIII of England's fifth wife, Catherine Howard (of noble but not sovereign ancestry), is known by her maiden surname, while George V's wife (a descendant of the sovereign ducal house of Württemburg) is commonly known as Mary of Teck (after her father's title), and Edward VII's wife (a daughter of the King of Denmark) is known as Alexandra of Denmark.

Title: English and British royal mistress
Content:  George I had divorced his wife Sophia Dorothea of Celle 20 years before his accession to the British throne, and thus brought with him to the Kingdom of Great Britain his long-established mistress: Ehrengard Melusine von der Schulenburg, who was so tall and scrawny that she was nicknamed "the maypole". Sophia von Kielmansegg, sometimes referred to as a mistress of George I, was actually his morganatic half-sister; they were both children of Ernest Augustus, Elector of Hanover. She was known to compete for influence with Melusine and assumed, or pretended, to be a mistress by the British courtiers.

Title: English and British royal mistress
Content:  His son George IV, first Prince Regent during George III's periods of insanity and then King following his death, carried on an affair of twenty years with a widow, Maria Fitzherbert, with whom he lived and considered his true wife. He was reported to have even married her, even though he became increasingly unfaithful and accepted the paternity of several illegitimate children throughout this time period. Afterwards, he rejected any possible marriage he might have made with Mrs. Fitzherbert. His other notable mistresses included Mary Robinson, Frances Twysden, Grace Elliott, Isabella Seymour-Conway, Marchioness of Hertford and Elizabeth Conyngham, Marchioness Conyngham. George IV and his legitimate wife Caroline of Brunswick were never fond of their arranged marriage and lived separately from 1796 to her death on 7 August 1821. Their only daughter Princess Charlotte of Wales was born very early in the marriage. That both George and Caroline took other lovers was not therefore unexpected. George survived his only legitimate daughter.
Title: Wedding of Prince George, Duke of Kent, and Princess Marina of Greece and Denmark
Content:  The wedding of Prince George, Duke of Kent, and Princess Marina of Greece and Denmark took place on Thursday, 29 November 1934 at Westminster Abbey. The Duke of Kent was the fourth son of King George V and Princess Mary of Teck, while Princess Marina was the youngest daughter of Prince Nicholas of Greece and Denmark and Grand Duchess Elena Vladimirovna of Russia. The couple were second cousins through mutual descent from King Christian IX of Denmark. As Princess Marina's cousin, Prince Philip, renounced his Greek and Danish titles prior to marrying Prince George's niece, then Princess Elizabeth, this is the most recent example of a marriage between a British prince or princess and a titled member of a foreign dynasty.
Title: King George and Queen Mary
Content:  I. The first episode recalls how, fearing anti-German sentiment, the royal house name was changed by King George from the House of Saxe-Coburg and Gotha to the House of Windsor. The series also examines the personal lives of the couple, delving into their relationships with their children, and with each other. The marriage between George and Mary was an arranged marriage, occurring only because Prince Albert Victor, George's brother and Mary's original fiancé, died from influenza. George V is presented in the series as a disciplinarian, who strictly punished his children, but was known to be much more loving to his granddaughter, Queen Elizabeth II.
