The book is a publication of the New England Historic Genealogical Society's (NEHGS) publication "New England Marriages Prior to 1700." Clearly people are looking for information about this wonderful publication. I wrote about it last year. (See here.)
So, why does that blog page show up between 1st and 2nd in the google rankings, usually ahead of Ancestry.com postings and the publisher NEHGS? I have no answer, but am pleased. The photo was taken at NEHGS recently, and shows a new 2011 publication (large maroon books) of the New England Marriages Prior to 1700.
From the NEHGS description of this series,
"This three-volume work of New England Marriages Prior to 1700 is a transcription of the complete text of Clarence Almon Torrey's twelve-volume handwritten manuscript, held by the
New England Historic Genealogical Society. Although 'Torrey' as it is familiarly known, has been published in book form previously, it has never before been printed in a format that includes all sources and a comprehensive every-name index."
