This book traces the descendants of John Gibson, a pioneer of 1634 in Cambridge, Massachusetts, over 6 generations to 1899, beginning with his son John who married into the old English family of Prentice. Each of his children had many descendants, and the book contains the names of several thousand Gibsons, their genealogies, dates, and places of birth, marriage, and death.

The introduction discusses the English and Scottish origins of the Gibson name, and the book also includes a fold-out genealogical chart of the Gibson family.
