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'Costagent is Mac Oistigin which is probably derived from the pet form of the English name Roger, which is Hodgkin.

O'Costagent Spelling Variations
During the Middle Ages, a standardized literary language known by the general population of Ireland
was a thing of fiction. When a person's name was recorded by one of the few literate scribes, it was up that particular scribe to decide how to spell an individual's name. So a person could have several spelling variations
of his name recorded during a single lifetime. Research into the name O'Costagent revealed many variations, including Costigan, Costigen, Costigin, McCostigan and others.

Migration of the O'Costagent family to the New World and Oceana
The 18th century saw the slow yet steady emigration of Irish families
to British North America and the United States. Those early Irish settlers that left their homeland were typically moderately well off: they were enticed by the promise of a sizable plot of land. However, by the 1840s, this pattern of immigration was gone: immigrants to North America were seeking refuge from the starvation and disease that the Great Potato Famine
of that decade brought. The great numbers of Irish that arrived to the United States and the soon to be Canada were instrumental in their quick development as powerful industrial nations. An examination of early immigration and passenger lists uncovered many early immigrants bearing the name O'Costagent: Michael, James, Joseph, Lawrence, Patt, Thomas (three of this name), and William Costigan, who arrived in Philadelphia, Pennsylvania between 1850 and 1870.
