This work, compiled over a period of thirty years from about 2,000 books and manuscripts, is a comprehensive listing of the 37,000 married couples who lived in New England between 1620 and 1700. Listed are the names of virtually every married couple living in New England before 1700, their marriage date or the birth year of a first child, the maiden names of 70% of the wives, the birth and death years of both partners, mention of earlier or later marriages, the residences of every couple and an index of names. The provision of the maiden names make it possible to identify the husbands of sisters, daughters, and many granddaughters of immigrants, and of immigrant sisters or kinswomen.

Family history and genealogical data, ca.1312-1880, for these three branches of the Wentworth family. After various earlier men in all three branches had been made knights, the Nettlestead family was given the title of "Baron" in 1529, and the Gosfield family in 1611.
