After their the nuptial mass in New York City's St. Patrick's Cathedral on Fifth Avenue, Kathy and Jack return with their wedding party to the bridegroom's old neighborhood on East 93rd Street. At one time, settled by Irish and Italians, it is now Puerto Rican.
Katrina Thomas's notes: The Scotch-Irish, who arrived in the 17th and 18th centuries, were Protestant. But a significant Irish Catholic immigration had been increasing yearly, millions arriving after the potato famine, so that by the 1840's they comprised nearly half of all immigrants. If both bride and bridegroom are Catholic, they may be married in a nuptial mass. I found no distinctive Irish customs to photograph at the celebration of marriages.
