Donahue is the Americanized version of Irish surname Donohoe, which, in turn, is an Anglicized version of the ancient Irish name "Donnchadh" (sometimes "Donncha").

Donncha was a common “first name” in 9th Century Ireland, and when the use of surnames became more common in Ireland around the 10th Century, many people looked to a respected common ancestor to form a surname. The ancestors of the modern Donahues took the name O’Donnchadha (pronounced “o-don-a-chu), of the line of Donnacha. However, these modern Donahues are not all descended from the same person named Donnacha; rather, the modern Donahues are likely descended from one of at least eight unrelated Donnachas, each of whose descendants adopted the surname O’Donnchadha.

There are eight known O'Donoghue ancient tribal areas in Ireland. They were in Munster: Tipperary, Cork/Kerry - Leinster: Kilkenny, Wicklow/Dublin, Meath - Connaught: Galway, Mayo/Sligo, Cavan. Considerable migration took place over the centuries and family groups took root in many other counties (eg Clare, Limerick, Waterford, Roscommon and others), which would today be recognised as their areas of origin.

Ayn Rand ( /ˈaɪn ˈrænd/; born Alisa Zinov'yevna Rosenbaum, February 2 [O.S. January 20] 1905 – March 6, 1982) was a Russian-American novelist, philosopher, playwright, and screenwriter. She is known for her two best-selling novels The Fountainhead and Atlas Shrugged and for developing a philosophical system she called Objectivism.

Born and educated in Russia, Rand moved to the United States in 1926. She worked as a screenwriter in Hollywood and had a play produced on Broadway in 1935–1936. After two initially unsuccessful early novels, she achieved fame with her 1943 novel The Fountainhead. In 1957, she published her best-known work, the philosophical novel Atlas Shrugged. Afterward she turned to nonfiction to promote her philosophy, publishing her own magazines and releasing several collections of essays until her death in 1982.

Rand advocated reason as the only means of acquiring knowledge and rejected all forms of faith and religion. She supported rational and ethical egoism, and rejected ethical altruism. In politics, she condemned the initiation of force as immoral and opposed all forms of collectivism and statism, instead supporting laissez-faire capitalism, which she believed was the only social system that protected individual rights. She promoted romantic realism in art. She was sharply critical of the philosophers and philosophical traditions known to her besides Aristotle.

Marilyn Manson (born Brian Hugh Warner; January 5, 1969) is an American musician, artist and former music journalist known for his controversial stage persona and image as the lead singer of the eponymous band Marilyn Manson. His stage name was formed from juxtaposing the names of two 1960s American cultural icons, namely actress Marilyn Monroe and convicted multiple murder convictCharles Manson as a critical and, simultaneously, laudatory appraisal of America and its peculiar culture. The seemingly outrageous styles for which he models and the controversy surrounding his lyrics have led to his public appeal.

Marilyn Manson was born in Canton, Ohio. He is the only child of Barbra Warner (maiden name Wyer) and Hugh Warner. Manson is of Polish and German descent on his father's side, and is a fourth cousin twice removed of Conservative commentator Pat Buchanan. In his autobiography The Long Hard Road Out of Hell, he detailed his grandfather's sexual fetishes (including bestiality and sadomasochism) which led to the forming of Marilyn Manson and the Spooky Kids.
