Virginia can be a genealogist's nightmare. This state from which so many American families sprang has been a maze of counties that hold or held vital records. Since its founding, at least 172 counties have existed in Virginia; at present there are about 100. Many were created from counties, and some have since merged with others, changed their names, or become parts of Kentucky and West Virginia. Well-aware of the problem of researching Virginia, Morgan P. Robinson early in this century compiled ``Virginia Counties: Those Resulting from Virginia Legislation,'' which appeared in 1916 in three issues of the ``Bulletin of the Virginia State Library.'' Republished in book form, this detailed and extensive collection of information is aimed at pointing you to the right places to find the vital data. The first part of the book lists the counties in chronological order of founding -- the first ones in 1634 and the last in 1880 -- and what each was formed from. The second part makes use of maps to show how counties were formed, and how settlement moved westward through the state. Finally, there is a ``genealogy'' of the state's counties, showing which counties sprang from which -- sometimes into four or five ``generations.'' There's also a general history of Virginia's county system, including how they got their names, and an extensive bibliography of county histories and historical articles, arranged by county. The entire 283-page volume is fully indexed. Anyone delving into Virginia records will find Mr. Robinson's work indispensable. Copies may be obtained from genealogical suppliers or societies, or directly from Genealogical Publishing Company, Dept. SM, 1001 North Calvert Street, Baltimore, MD 21202-3897 (1-800-296-6687).
