The Abbe genealogy, as here published, is the consummation of Professor Cleveland Abbe’s life-long interest in the history of his family. Before reaching his twentieth year he began to collect items of interest about his ancestors and the collateral lines, and in spite of more or less interruption he has continued to do so all through his busy career. From time to time other members of the family added to the items collected by or worked up at the suggestion of Professor Abbe. A few years ago, finally realizing that other matters demanded too much time and that he could not arrange this material in final form, he turned over all his material to Josephine Genung Nichols. She has arranged the data in its present form, and added to it, as far as practicable, by extensive correspondence, library research and examinations of the public records at some of the former homes of the family.
