Anderson, Robert. A Closer Look at the Great Migration Study Project, New England Ancestors, Fall 2001.
The primary mission of the Great Migration Study Project has been to serve as a guide to what is known about each of the immigrants to New England between 1620 and 1643 and to replace the many older reference works we have for these families.
At a very early stages of the project, we developed a sketch format to organize our biographical and genealogical knowledge of each of the immigrants. This format has stood up well over the years, but the material included under each heading within a sketch has undergone changes. Most importantly, the original plan was to include a list of the names of the children of each immigrant, with only birth or baptismal data attached; but David Greene (who, along with Robert Wakefield and Roger Joslyn, has been from the beginning of the project one of the readers of sketch drafts) soon insisted that more detail be given for the children, including especially their marriages, but also other information where relevant.
Other changes have been made as well. In the section on "Offices," there has been a steady trend to present the data in a more rational form, with civil offices given first, and then military offices, and within each of those subsections, the material was further divided by the jurisdiction within which the service was performed.
