Hibernia is a village in Rockaway Twp. which was once a thriving ironworks in the 18th and 19th century. At one point it was self-sufficient and still retains its post office status. Here are two theories regarding how it got its name. One is due to the large amount of Irish Catholics working there (The church was even named St. Patrick's).But most of the Irish came long after the area was named. Second (and I think more plausible) Samuel Ford, one of the original owners of the mine in 1765 (a one of the first counterfeiters) visited Ireland and was so enamoured of the country (he even committed bigamy by marrying an Irish lass), he renamed the his works.
