TAKE A WALK THRU TIME : "
The majority of the information that has been typed into this website is from a book that was published in 1879.The name of the book is 'Descendants of William Sumner of Dorchester Mass.' by William Sumner Appleton.

In 1854 was printed, for Gen.William H. Sumner of Roxbury, a 'Memoir of Increase Sumner, Governor of Massachusetts,' to which was added a 'Genealogy of the Sumner Family, by William B. Trask.' Some additions were printed in the N.E. Historical and Genealogical Register, for October, 1855. Mr. Trask was entirely competent to have prepared a genealogy, which would have made this present volume unnecessary; but Gen. Sumner was willing only to have very limited researches made, concerning principally the branches most nearly related to his own. The 'Genealogy' therefore is exceedingly imperfect, and so misleading as to cause one to suppose the family a very small one; and it was in consequence of this mistake that the present writer undertook the work, which has grown in progress to an extent never dreamt of, or it would probably not have been begun. Once under way, however, interest has kept pace with material, and I feel no regret for the time given to the work, or the trouble which has of necessity accompanied it.
