This is a collection of genealogies of the early settlers of "Old Hunterdon County," New Jersey, the majority of the histories tracing families through successive generations of the 18th and 19th centuries in what is now mostly Mercer County. Composed chiefly of a recitation of births, marriages, and deaths, the family histories number more than sixty and touch on several thousand related persons, all of whom are conveniently cited in the index.
