Virtually anyone doing genealogical or historical research in English-language records pertaining to America will find this compilation of words and phrases useful. It is not limited to a particular time period, geographical area, or ethnic group but to all aspects of the country's settlement. Among the terms included are medical, legal, religious, relational, colloquial, foreign, occupational, monetary, and household. This is a reference you should keep close at hand, whether working at home or on the road; you never know when you are going to need it. It is the latest edition and the largest the author produced.
If you are a professional genealogist or just your family's historian, this book is very, very helpful. The sub-title is "A Comprehensive Dictionary for Genealogists and Historians," and that is an accurate description.
Terms have changed and can drive a researcher crazy. When is a "cousin," not a cousin? What the heck is a "cousin german" when your family came from Ireland? Was your great-grandpappy a "knockknobbler?" What is the difference between a "consort" and a "relict?" As a professional genealogist, I couldn't work without this handy book beside my computer!
