Following the 1995 publication of A Crocker Genealogy, a great deal of related information began coming to light. This, along with a number of recent births, has prompted the release of this second volume, which is a companion or supplement to Volume 1. To trace each addition or correction included in this volume, readers will need to refer to Volume 1. Each addition or correction is headed with the relevant page number in Volume 1, followed by a source code, followed by the Henry system identification number for the individual in question, followed by the new information.
