While the Anglicized versions of Irish names are familiar to most people, many Irish names have a long and proud Gaelic heritage that is often unknown. The original Gaelic form of the name O'Costagon is Mac Oistigin which is probably derived from the pet form of the English name Roger, which is Hodgkin.

Migration of the O'Costagon family to the New World and Oceana
The English-ruled Ireland
of the late 18th and 19th centuries featured a rapidly increasing population and an agricultural-based economy. This combination proved to be disastrous in the 1840s after a couple of failed potato harvests. Thousands died of disease and starvation, and thousands more left the country, often bound for North America. Those that survived the journey to North America were put to work building the bridges, canals, roadways, and railways needed for the development of an industrial society. Those Irish, although often despised by those already established in North American cities and towns, played an instrumental role in making Canada and the United States the powerful and wealthy nations that they are today. An examination of early immigration and passenger lists has shown many immigrants bearing the name O'Costagon: Michael, James, Joseph, Lawrence, Patt, Thomas (three of this name), and William Costigan, who arrived in Philadelphia, Pennsylvania between 1850 and 1870.
