I have looked through Vol. II and could not find any additional references to either Samuel Jr. or Betsey Thomas or Aurelia Tower. Perhaps you will find something in Vol. III. I have heard that all the volumes are in the library in Hingham, MA. Also, TGS does not have a building, so there is no exact location. One of our directors, Bernard E. Tower and his brothers reconstituted the original Tower Genealogical Society (1909) in 1976. We have members all over the United States. I hope you will join us at Hingham in 2009.
