Her father was Edward Yeamans, a circus clown.  The Yeamans family came from Australia and toured China, Japan and Java in traveling shows before arriving in San Francisco in 1865.  After arriving in America, Edward Yeamans died in 1866 or '68. Pauline McLynn (born 11 July 1962) is an Irish character actress and author.

The programme was created and partially written by Paul Abbott, who is also the programme's executive producer.  In 2005, the show won "Best Drama Series" at the BAFTA TV Awards and "Best TV Comedy Drama" at the British Comedy Awards.

A breeches role (also pants role or trouser role, "travesti" or "Hosenrolle") is a role in which an actress appears in male clothing.

Age of Consent (also known as Norman Lindsay's Age of Consent) is a 1969 Australian film which was the penultimate feature film directed by British director Michael Powell.  The romantic comedy-drama stars James Mason (co-producer with Powell), Helen Mirren in her first major film role, and Irish character actor Jack MacGowran and features actress Neva Carr Glyn.  The screenplay by Peter Yeldham was adapted from the 1935 semi-autobiographical novel of the same name by Norman Lindsay, who died the year this film was released.  Lindsay is also portrayed (in this case, by name) in the 1994 film "Sirens", starring Hugh Grant, Sam Neill, and Elle Macpherson. Cigfa ferch Gwyn Glohoyw (Middle Welsh: "Kigua") is a minor character in Welsh mythology, the wife of King Pryderi of Dyfed.  She is mentioned briefly in the First Branch of the "Mabinogi", and appears more prominently in the third.  Describing the character, Proinsias Mac Cana writes: "Cigfa strikes one as a slight though effective vignette of a contemporary bourgeois snob while William John Gruffydd hypothesises that the character was a later addition to the tale."  John Rhys suggested a connection between Cigfa and the Irish character "Ciochba". Valerie Lilley (born 14 April 1939) is a Northern Irish actress who has played many television roles on dramas such as "Doctors" and "Grange Hill".
