Silver's Circus, the original, was an (Australian) circus started by Mervyn King along with tentmakers, David Hardie Snr.
 and his two sons Les and David Jnr.
 King, an orphan, was given to St. Leons Circus at the age of seven.He spent his entire life performing in the ring and became one of the Australian Circus' best known animal trainers and acrobats.
 He started Silver's circus in 1946 by breaking in a first class lion act, buying and training show horses, surplus army tents and other equipment.
 It became one of the most well organised best looking and popular circuses in the country.
 It also was the first to cross the Nullarbor by road, then a corrugated dirt track full of potholes and bulldust.
 King changed his stage name to Alwyn Silver to reflect the circus.
 King sold Silver's in 1953, admitting later the sale was premature since TV didn't make much of an impact on Australian rural life until well into the 1960s.
 He saw television as a threat.
 Mervyn King had two sons.
 He died in 2003 at age 96.
Hatshepsut’s royal lineage was established through her parents, Thutmose I her father and The Great Royal Wife Ahmose, her mother.
 Thutmose I had two sons and a daughter, Amenmose, Wadjmose and Hatshepsut, through Ahmose.
 Egyptian hierarchy established the eldest sons as heirs to the throne; however, with the death of these two sons at an early age, it is still possible to produce a son through a secondary wife or lesser wife.
 Mutnofret, Thutmose I’s secondary wife gave birth to a son, Thutmose II, giving him lineage to the throne.
 To legitimize Thutmose II’s reign, he married his half-sister Hatshepsut, who carried the royal Ahmose blood line.
 Through this marriage Hatshepsut was given her royal titles as Great King’s Wife and God’s Wife of Amun that gave her royal responsibilities to appear and participate in cult rituals.
The Three Witches or Weird Sisters or Wayward Sisters are characters in William Shakespeare's play "Macbeth" (c. 1603–1607).
 They hold a striking resemblance to the three "Fates" (in Greek mythology), and are, perhaps, intended as a twisted version of the white-robed incarnations of destiny.
 The witches eventually lead Macbeth to his demise.
 Their origin lies in "Holinshed's Chronicles" (1587), a history of England, Scotland and Ireland.
 Other possible sources, aside from Shakespeare's imagination itself, include British folklore, such contemporary treatises on witchcraft as King James VI of Scotland's "Daemonologie", the Norns of Norse mythology, and ancient classical myths of the Fates: the Greek Moirai and the Roman Parcae.
 Productions of "Macbeth" began incorporating portions of Thomas Middleton's contemporaneous play, "The Witch", "circa" 1618, two years after Shakespeare's death.

Macbeth (or The Tragedy of Macbeth) is a 1971 British-American historical drama film directed by Roman Polanski and co-written by Polanski and Kenneth Tynan.
 A film adaptation of William Shakespeare's tragedy of the same name, it retells the story of the Highland lord who becomes King of Scotland through treachery and murder.
 The film stars Jon Finch as the title character and Francesca Annis as Lady Macbeth, noted for their relative youth as actors.
 Themes of historic recurrence, greater pessimism and internal ugliness in physically beautiful characters are added to Shakespeare's story of moral decline, which is presented in a more realistic style.
Lord Banquo , the Thane of Lochaber, is a character in William Shakespeare's 1606 play "Macbeth".
 In the play, he is at first an ally to Macbeth (both are generals in the King's army) and they are together when they meet the Three Witches.
 After prophesying that Macbeth will become king, the witches tell Banquo that he will not be king himself, but that his descendants will be.
 Later, Macbeth in his lust for power sees Banquo as a threat and has him murdered; Banquo's son, Fleance, escapes.
 Banquo's ghost returns in a later scene, causing Macbeth to react with alarm during a public feast.
Domnall Gerrlámhach (died 1135), also known as Domnall Gerrlámhach Ua Briain, Domnall mac Muirchertaig, and Domnall Ua Briain, was an obscure twelfth-century Uí Briain dynast and King of Dublin.
 He was one of two sons of Muirchertach Ua Briain, High King of Ireland.
 Domnall's father appears to have installed him as King of Dublin in the late eleventh- or early twelfth century, which suggests that he was his father's successor-designate.
 Although Domnall won a remarkable victory in the defence of the Kingdom of Dublin in the face of an invasion from the Kingdom of Leinster in 1115, he failed to achieve the successes of his father.
 After his final expulsion from Dublin at hands of Toirdelbach Ua Conchobair, King of Connacht, and the death of his father, Domnall disappears from record until his own death in 1135.
 He was perhaps survived by two sons.
Jennifer Finney Boylan (born June 22, 1958) is an American author and political activist.
 In 2014 she joined the faculty of Barnard College of Columbia University as the Anna Quindlen Writer-in-Residence, having previously been professor of English at Colby College in Maine.
 She is a trans woman.
 Her 2003 autobiography, "She's Not There: A Life in Two Genders", was the first book by an openly transgender American to become a bestseller.
 She has two sons, Zach and Sean, with Deirdre Boylan whom she married in 1988 as James Boylan.
 Jennifer began her male to female transition in the year 2000.
 The transformation started with therapy, feminine clothing, and then taking female hormones.
 While undergoing sexual reassignment surgery Jennifer feared that her marriage to Deirdre would certainly come to an end.
 Today, the couple is still married and residing between New York City and Belgrade Lakes, Maine, with their two sons.
 Nine years after she began her transition she published an article for "The New York Times" claiming, "my spouse and I love each other, and that our legal union has been a good thing – for us, for our children and our community".
 She made appearances as a friend of Caitlyn Jenner on the reality television show "I Am Cait".
King Duncan is a fictional character in Shakespeare's "Macbeth."
 He is the father of two youthful sons (Malcolm and Donalbain), and the victim of a well-plotted regicide in a power grab by his trusted captain Macbeth.
 The origin of the character lies in a narrative of the historical Donnchad mac Crinain, King of Scots, in Raphael Holinshed's 1587 "The Chronicles of England, Scotland, and Ireland," a history of Britain familiar to Shakespeare and his contemporaries.
 Unlike Holinshed's incompetent King Duncan (who is credited in the narrative with a "feeble and slothful administration"), Shakespeare's King Duncan is crafted as a sensitive, insightful, and generous father-figure whose murder grieves Scotland and is accounted the cause of turmoil in the natural world.
Donnchad mac Crinain (Modern Gaelic: "Donnchadh mac Crìonain"; anglicised as Duncan I, and nicknamed An t-Ilgarach, "the Diseased" or "the Sick"; ca. 1001 – 14 August 1040) was king of Scotland ("Alba") from 1034 to 1040.
 He is the historical basis of the "King Duncan" in Shakespeare's play "Macbeth".

Question: What are the two sons of the King featured in Shakespeare's Macbeth?
Answer: Malcolm and Donalbain
