Baron Mount Temple was a title that was created twice in British history, both times in the Peerage of the United Kingdom.
 The first creation came on 25 May 1880 when the Liberal politician the Honourable William Cowper-Temple was made Baron Mount Temple, of Mount Temple in the County of Sligo.
 He was born William Cowper, the second son of Peter Clavering-Cowper, 5th Earl Cowper (see Earl Cowper for earlier history of the family) by his wife the Honourable Emily, sister of The 2nd Viscount Melbourne.
 Emily married as her second husband The 3rd Viscount Palmerston, a man who would serve as British Prime Minister.
 Lord Palmerston, an Anglo-Irish peer, died in 1865 when the viscountcy and his junior title of Baron Temple, of Mount Temple, became extinct.
 Emily died 11 September 1869, leaving her second husband's estates, including Broadlands in Hampshire, to her second son, William, who thereupon adopted by Royal licence the surname Cowper-Temple, in whose favour the Mount Temple title was revived in 1880.
Baron Greenwich is a title that has been created twice in British history.

 She was the daughter of Field Marshal John Campbell, 2nd Duke of Argyll, who had been created Earl of Greenwich in 1715 and Duke of Greenwich in 1719, titles which became extinct on his death in 1743.
 As Caroline's two sons by her second husband predeceased her, the title became extinct upon her death in 1794.

Mary Madeline "May" Bonfils Stanton (April 30, 1883 – March 11, 1962) was an American heiress and philanthropist.
 She and her younger sister, Helen Bonfils, succeeded their father, Frederick Gilmer Bonfils, as principal owners of "The Denver Post".
 However, May's elopement at age 21 with a non-Catholic salesman had forged a rift in her relationship with her parents and sister that worsened when Helen inherited the lion's share of their parents' estates.
 Following a three-year legal battle over the inheritance, the sisters cut off all communication with each other.
 May married twice but did not have children.
 Living a reclusive life, she invested her fortune into building and furnishing her 750 acre estate in Lakewood, Colorado – which included a mansion that was an exact replica of Marie Antoinette's Petit Trianon château in Versailles – and into many philanthropic endeavors in the state of Colorado.
 The Bonfils–Stanton Foundation, established by her second husband after her death in 1962, continues to support the arts in Colorado.
 She was posthumously inducted into the Colorado Women's Hall of Fame in 1985.
Sigrid the Haughty, also known as Sigríð Storråda, is a queen appearing in Norse sagas as wife, first of Eric the Victorious of Sweden, then Sweyn Forkbeard of Denmark.
 Sigrid appears in many sagas composed generations after the events they describe, but there is no reliable evidence as to her existence as they describe her.
 The figure of Sigrid appears mainly in late Icelandic sagas, while more contemporary sources such as Thietmar of Merseburg and Adam of Bremen instead claim that Sweyn was married to a Polish princess, identified as Świętosława.
 Snorri Sturlason gives conflicting information and in one place says that Sweyn was married to Sigrid and in another that he was married to a Gunhild of Wenden.
Cleopatra's Second Husband is a 1998 psychological drama written, produced and directed by Jon Reiss.
 Paul Hipp (The Funeral) and Bitty Schram (Kissing a Fool) play Robert and Hallie Marrs, a young LA couple, who go on vacation, leaving their house in the hands of strangers.
 They return to find their fish as dead as the plants, everything in disarray, and housesitters, clad in the couple's clothes, refusing to leave.
 Zack (Boyd Kestner) and Sophie (Radha Mitchell), the charismatic house sitting couple, soon infuse the repressed Robert with their erotically perverse irresponsibility.
 Robert, browbeaten and seemingly devoid of personality (with even his sex life regulated by his domineering wife's ovulation cycle), is easily seduced by the sexy Sophie.
 When Hallie discovers the dalliance and leaves, Robert literally becomes the couples slave.
 He gives them control of his home, his credit cards, practically his entire identity, until one day, driven to the darkest edge of his psyche, he snaps.
 Partially inspired by a true incident, this gripping thriller is equal parts black comedy and psychological power play.
 The films title "Cleopatra's Second Husband," derives from Hallie and Robert's relationship which is a parallel to that of Cleopatra and Marc Antony.
