With over 80,000 entries, 10,000 brand new, and thousands more revised and expanded, the second edition of the Dictionary of American Family Names explains the meanings of the family names for more than 90 percent of the US population. The product of seventeen years of exhaustive research, the dictionary provides comparative frequencies, linguistic and historical explanations, selected associated forenames, and occasional genealogical notes, revealing the meanings of names, some intuitive, some amusing, and some quite surprising.
