Here's a brief quote from the Preface, page xi, that mentions some family members:
Mrs. Abel Nichols, not to mention others, was of North Danvers, and she and her husband were among the best of abolitionists. Their daughter, the late Mrs. Eben G. Berry, recalled with what fear and trembling she was wont, as a young girl, to circulate anti-slavery documents, and their nephew, Mr. Andrew Nichols, now of Danvers, son of Dr. Andrew Nichols, remembers how he used to be stoned in the streets for procuring subscribers to anti-slavery papers.
