Question:  St. Mary's Ukrainian Catholic Church is located in a country that covers five-eighths of what?
Context: England is a country that is part of the United Kingdom.  It shares land borders with Scotland to the north and Wales to the west.  The Irish Sea lies northwest of England and the Celtic Sea lies to the southwest.  England is separated from continental Europe by the North Sea to the east and the English Channel to the south.  The country covers five-eighths of the island of Great Britain (which lies in the North Atlantic) in its centre and south, and includes over 100 smaller islands such as the Isles of Scilly and the Isle of Wight. St. Mary's Catholic Church is a church located on the corner of Transit (New York State Route 78) and Stahley roads in Swormville, New York, in the United States.  Originally known as St. Mary’s Church of the Assumption at Transit, the building was constructed of about 260,000 bricks.  John Nepomucene Neumann (later to be named St. John Neumann) started to visit Swormville, celebrating mass in local homes, barns and fields.  In 1839 he instructed that a small house would be made to hold mass.  Bishop John Timon established the first catholic church (St. Mary's) of the town of Clarence, New York.  In 1861, Father Michael Schinabeak made plans for a church to be constructed.  Construction began in 1862 and finished in fall of 1865.  The official opening of the Church was in January 1866.  In 2010 a new Church was constructed behind the old St. Mary's. Our Lady of Pochaev and St Andrew's Ukrainian Catholic Church is situated on Dalmeny Street, Leith.  It is one of the few Ukrainian Greek Catholic parish churches in Scotland.  It is a church in the only Eastern Catholic eparchy in Great Britain, the Ukrainian Catholic Eparchy of the Holy Family of London. St. George Ukrainian Catholic Church (Ukrainian: Українська Католицька Церква Св.  Юра ) is a Ukrainian Greek Catholic Church located in the East Village neighborhood of New York City's borough of Manhattan.  Situated at the corner of East 7th Street and Taras Shevchenko Place, the church and the adjoining St. George Academy are encircled by, but not included in, the East Village Historic District.  For over 100 years, this Ukrainian parish has served as a spiritual, political and cultural epicenter for several waves of Ukrainian Americans in New York City. The Western Ukrainian clergy of the Ukrainian Greek Catholic Church were a hereditary tight-knit social caste that dominated Western Ukrainian society from the late eighteenth until the mid-twentieth centuries, following the reforms instituted by Joseph II, Emperor of Austria.  Because, like their Orthodox brethren, Ukrainian Catholic priests could marry, they were able to establish "priestly dynasties", often associated with specific regions, for many generations.  Numbering approximately 2,000-2,500 by the 19th century, priestly families tended to marry within their group, constituting a tight-knit hereditary caste.  In the absence of a significant culturally and politically active native nobility (although there was considerable overlap, with more than half of the clerical families also being of petty noble origin ), and enjoying a virtual monopoly on education and wealth within western Ukrainian society, the clergy came to form that group's native aristocracy.  The clergy adopted Austria's role for them as bringers of culture and education to the Ukrainian countryside.  Most Ukrainian social and political movements in Austrian-controlled territory emerged or were highly influenced by the clergy themselves or by their children.  This influence was so great that western Ukrainians were accused by their Polish rivals of wanting to create a theocracy in western Ukraine.  The central role played by the Ukrainian clergy or their children in western Ukrainian society would weaken somewhat at the end of the nineteenth century but would continue until the Soviet Union forcibly dissolved the Ukrainian Greek Catholic Church in Ukrainian territories in the mid-twentieth century (the so-called Council of Lviv, 1946). The Syro-Malabar Catholic Church (Syriac: ܥܹܕܬܵܐ ܕܡܲܠܲܒܵܪ ܣܘܼܪܝܵܝܵܐ‎ , "Edtha d'Malabar Suryaya"; , "sīṟēā malabār kattēālikkā sabha") or Church of Malabar Syrian Catholics is an Eastern Catholic Major Archiepiscopal Church based in Kerala, India.  It's a "sui iuris" particular church in full communion with the Pope and the worldwide Catholic Church, with self-governance under the Code of Canons of the Eastern Churches.  The Church is headed by Major Archbishop Cardinal Mar George Alencherry of the Archeparchy of Ernakulam-Angamaly in Kerala.  The Syro-Malabar Church uses a latinized variant of the Liturgy of Saints Addai and Mari belonging to the East Syrian Rite, which dates back to 3rd century Edessa, as such it is a part of Syriac Christianity by liturgy and heritage.  The name Syro-Malabar is coined from the words Syriac (referring to the East Syriac liturgy) and Malabar (the historical name for Kerala).  The name has been in usage in official Vatican documents since the nineteenth century.  The Church shares the same liturgy with the Chaldean Catholic Church based in Iraq.  It is the third-largest particular church ("sui juris") in the Catholic Church (after the Latin or Roman Church and the Byzantine Rite Ukrainian Catholic Church).
