This is a genealogy of Michael Bacon of Dedham and his descendants. Michael arrived in Dedham, Massachusetts in 1640 after sailing aboard an unnamed ship, likely from County of Suffolk, England, but possibly from Ireland. Baldwin treats the descendants of each of the three sons of Michael—Michael Jr., Daniel, and John—in a separate chapter, the first chapter being devoted to Michael Sr. and his English roots. The early descendants settled in Bedford, Billerica, Bridgewater, Cambridge, Dedham, Newton, Salem, Watertown, and Woburn Massachusetts.
Bacon Genealogy
Preface by Author
Having been interested for the past few years in looking up records of Bacon families who trace their descent from Michael of Dedham in 1640, and having accumulated considerable material, I decided to publish the same so that the result of my labors might be accessible to any who might be interested. These records have been gathered from various sources: from town records, town histories, and genealogies of allied families, and in many cases from family records and Bibles. Some records that have been obtained would not be available in a few years after the death of those now living, and only in this way will they be preserved. In the scattering of families in the eighteenth century all trace of many has been lost, and it has not been possible to complete their line. In some of these cases where they have been located, failure to answer letters of inquiry sent to them has broken the line at that point. Undoubtedly errors may be found, but in a work of this size it is hard to eliminate them entirely. In several accounts of parts of the family heretofore published errors occur, in that descendants of other lines not connected with Michael have been wrongly attributed to his line. These errors I have tried to avoid, and in these instances my work will not be in agreement with the accounts above alluded to.
