A comprehensive, well-documented genealogy of the descendants of Gerrit, Lambert, and Elias Dorland, early settlers of New Netherland/New York. In addition to the male-lines, descendants of daughters are traced, in some cases for many generations. These families migrated early in large numbers to New Jersey, Pennsylvania, Kentucky, New York, Ohio, Indiana, Missouri, California and Oregon, as well as Canada. Many errors in earlier accounts of the Dorlands are corrected.
