St. Mary's Church (Swormville, New York): 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.

St. George's Church (Manhattan): St. George Ukrainian Catholic Church (Ukrainian: Українська Католицька Церква Св.

Western Ukrainian clergy: 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 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.
