Context: Y Wladfa (] , "The Colony"), also occasionally Y Wladychfa Gymreig, is a Welsh settlement in Argentina, which began in 1865 and occurred mainly along the coast of Chubut Province in the far southern region of Patagonia. Dolavon (Welsh: "Dolafon") is a small town in the Patagonian province of Chubut, Argentina.  It has a population of 2,929 according to the 2001 census .  It is located close to the Chubut River, about 19 km to the west of Gaiman.  The name comes from Welsh "dôl" (meadow) and "afon" (river).  Welsh immigrants began to settle in the area after their arrival in Patagonia in 1865.  The Central Chubut Railway arrived in 1915, linking the settlement to Trelew, and the town was officially founded in 1919.  Dolavon became a centre of wheat production using irrigation canals to compensate for the arid climate.  The old flour mill with its water wheel is now a museum. Patagonia is a 2010 British-Argentine drama film co-written and directed by Marc Evans.  The story centers on Welsh and Argentine people connected to "Y Wladfa", the Welsh settlement in Patagonia, Argentina.  The film stars several well-known Welsh actors including Matthew Rhys, Nia Roberts and the singer Duffy.  It premiered at the Seattle International Film Festival on 10 June 2010 and had its UK premiere in Cardiff on 4 March 2011. The Chubut River (Spanish: "Río Chubut" , Welsh: "Afon Camwy" ) is located in the Patagonia region of southern Argentina.  Its name comes from the Tehuelche word "chupat", which means "transparent".  The Argentine Chubut Province, through which the river flows, is named after it.  Welsh settlers called the river "Afon Camwy," meaning "twisting river" in English. The Welsh Tract, also called the Welsh Barony, was a portion of the U.S. state of Pennsylvania settled largely by Welsh-speaking Quakers.  It is located to the west of Philadelphia.  The original settlers, led by John Roberts, negotiated with William Penn in 1684 to constitute the Tract as a separate county whose local government would use the Welsh language.  The Barony was never formally created, but the many Welsh settlers gave their communities Welsh names that survive today.  A more successful attempt at setting up a Gwladfa (Welsh-speaking colony) occurred two centuries later, in the Chubut Province of Patagonia, Argentina. Patagonian Welsh (Welsh: "Cymraeg y Wladfa") is the name given to the Welsh language as spoken in Y Wladfa, the Welsh settlement in Patagonia, Argentina, specifically in the province of Chubut.  There is no evidence to suggest there are still any first language speakers remaining.  Claims about the number of native speakers refer to second language speakers or language learners. The San Matias Gulf is an inlet of the Atlantic Ocean off the coast of Patagonia, Argentina.  It is bordered by the Río Negro Province to the north and west, and the Valdes Peninsula of the Chubut Province to the south.  It is "one of the largest gulfs in the Patagonia region".  The gulf is surrounded by plateaus and depressions below sea level similar to the gulf itself but that are not flooded by the sea at present. Dr. Guillermo Rawson (24 June 1821 - 20 January 1890) was a medical doctor and politician in nineteenth-century Argentina.  As Interior Minister in 1862 he met Captain Love Jones-Parry and Lewis Jones who were on their way to Patagonia to investigate whether it was suitable for the creation of a Welsh settlement there.  Rawson came to an agreement with them, and this resulted in the creation of a colony in the Chubut Valley in the following years.  The city of Rawson, the capital of the province of Chubut was named after him. Ysgol yr Hendre ] is a Welsh/Spanish medium school in the large town of Trelew in Chubut Patagonia.  It was opened on Monday, 6 March 2006, initially to teach children between three and five years of age in Welsh and Spanish.  It is one of several active Welsh schools and nurseries.  The school was part of a 21st-century revival in Welsh in "the Welsh colony" Y Wladfa on the Chubut River (Camwy in Welsh).  In 2005 there were 62 Welsh classes in Chubut, and Welsh was on the curriculum of two primary schools and two colleges in the Gaiman catchment area.
