The American Genealogical-Biographical Index (AGBI) on Ancestry has this record which states:
Name: Hepzibah Mason
Volume: 111
Page Number: 364
Reference: Gregory Stone gen. Anc. and des. Of Dea. Gregory Stone of Cambridge, Ms. 1320-1917. By J. Gardiner Bartlett. Boston. 1918. (905p.):168
I located Gregory Stone genealogy : ancestry and descendants of Dea. Gregory Stone of Cambridge, Mass., 1320-1917 on ancestry and searched for Hepzibah Mason but am unable to find it. I checked page 364, I checked the index, I checked her maiden name, Hepziabah Eve, but cannot find any mention of her in the book.
Where can I locate the record in the book referred to by the AGBI?
