Rose Mary Barton {'1': ", '2': ", '3': 'RWS', '4': "} (Dublin 21 April 1856 – 1929) was an Anglo-Irish artist, a watercolourist who painted landscape, street scenes, gardens, child portraiture and illustrations of the townscape of Britain and Ireland.
 Barton exhibited with a number of different painting societies, most notably the Watercolour Society of Ireland (WCSI), the Royal Academy (RA), the Royal Hibernian Academy (RHA), the Society of Women Artists and the Royal Watercolour Society (RWS).
 She became a full member of the RWS in 1911.
 Her paintings are in public collections of Irish painting in both Ireland and Britain, including the National Gallery of Ireland and Dublin City Gallery The Hugh Lane in Dublin, and the Ulster Museum in Belfast.
Verity Mary Barton (born 6 August 1985) is an Australian politician who is the LNP member of the Legislative Assembly of Queensland for Broadwater, having defeated Peta-Kaye Croft at the 2012 state election.
Mary Barton founded a fertility clinic in Portland Place, London and later in Wimpole Street London with her husband Bertold Wiesner in the late 1930s and it did not close until 1967.
 It is assumed that all records were destroyed when the practice closed.
 The clinic pioneered artificial insemination using donor sperm for women whose husbands may have been infertile.
 The clinic helped women conceive 1,500 babies, nicknamed the 'Barton Brood', although the exact records appear to have been destroyed in 1963 owing to the social taboos and lack of regulation surrounding the subject.
Syrian nationality law is the law governing the acquisition, transmission and loss of Syrian citizenship.
 Syrian citizenship is the status of being a citizen of the Republic of Syria and it can be obtained by birth or naturalisation.
 The Syrian nationality is transmitted by paternity (father) (see Jus sanguinis).
 Therefore, Syrian nationality is determined solely by the father's nationality, while the place of birth is irrelevant.
 In other words, birthright citizenship is not recognized since being born in Syria does not grant an automatic right to become a national.
 In most cases, individuals are deemed to be Syrian nationals regardless of whether they are born inside or outside Syria as long as their father holds Syrian nationality.
Mary Barton is the first novel by English author Elizabeth Gaskell, published in 1848.
 The story is set in the English city of Manchester between 1839 and 1842, and deals with the difficulties faced by the Victorian working class.
 It is subtitled "A Tale of Manchester Life".
The Clara Barton Homestead, also known as the Clara Barton Birthplace Museum, is a historic house museum at 60 Clara Barton Road in Oxford, Massachusetts.
 The museum celebrates the life and activities of Clara Barton (1821-1912), founder of the American Red Cross.
 She was born in this modest farmhouse, which was built by her father, Captain Stephen Barton, member of a prominent local family, in 1818.
 Barton lived here until 1853.
Elizabeth Cleghorn Gaskell, ("née" Stevenson; 29 September 1810 – 12 November 1865), often referred to as Mrs Gaskell, was an English novelist, biographer, and short story writer.
 Her novels offer a detailed portrait of the lives of many strata of Victorian society, including the very poor, and are of interest to social historians as well as lovers of literature.
 Her first novel, "Mary Barton", was published in 1848.
 Gaskell's "The Life of Charlotte Brontë", published in 1857, was the first biography of Brontë.
 Some of Gaskell's best known novels are "Cranford" (1851–53), "North and South" (1854–55), and "Wives and Daughters" (1865).
