It should go without saying that to research genealogy effectively, one must learn history.  What better way to do so then to read a book on the area where your ancestor lived?  

"Through Eleven Decades.." is a history which presents the usual topics (such as churches, schools, and institutions) in an unusual manner.  After an introductory account on the subject, biographical sketches of the founders lives follows.  Additionally, there are entertaining stories as well to hold the attention such as "An Oriental Funeral" and "A Wedding Trip."   This book is a 'must have' for those researching in Watertown.
