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

Migration of the O'Costagane family to the New World and Oceana


Many destitute Irish families in the 18th and 19th centuries decided to leave their homeland, which had in many ways been scarred by English colonial rule. One of the most frequent destinations for these families was North America where it was possible for an Irish family to own their own parcel of land. Many of the early settlers did find land awaiting them in British North America, or even later in America, but for the majority of immigrants that arrived as a result of the Great Potato Famine of the late 1840s the ownership of land was often a long way off. These Irish people were initially put to work on such industrial projects as the building of bridges, canals, and railroads, or they worked at manufacturing positions within factories. Whenever they arrived, the Irish made enormous contributions to the infant nations of Canada and the United States. Some of the earliest immigrants to bearer the name of O'Costagane were found through extensive research of immigration and passenger lists: Michael, James, Joseph, Lawrence, Patt, Thomas (three of this name), and William Costigan, who arrived in Philadelphia, Pennsylvania between 1850 and 1870.
