Hi Sam, The "History of Washington County, Tn - 1988" is one large - large book. Besides the county history, it contains family history for 'hundreds"? of Tenn. families that have chosen to add their family history to the book. They are in alphabetical order and contain two or three hundred years of family history if the family has researched back that far - You need to ask for a specific surname and/or family name when requesting info. I believe the book sells now for about $55-60.00 thru the Museum in Jonesborough, TN. Jan W.
