A number of the Ireton families in New Jersey may be descendants of Obadiah Ireton, who immigrated to New Jersey from England before 1690 and died in New Jersey in 1711. There is no relationship proven between most families listed or to Obadiah Ireton (d. 1711). Descendants of Ireton families listed lived in New Jersey, Ohio, Indiana, Michigan, Kansas, Kentucky, and elsewhere.

This "Supplement to Genealogies in the Library of Congress" lists all genealogies in the Library of Congress that were catalogued between 1972 and 1976, showing acquisitions made by the Library in the five years since publication of the original two-volume Bibliography. Arranged alphabetically by family name, it adds several thousand works to the canon, clinching the Bibliography's position as the premier finding-aid in genealogy.
