Twenty-five years in the making, the Compendium of Early Mohawk Valley Families is nothing less than a complete and concise record of every family known to have lived in New York's Mohawk Valley in the 18th and early 19th centuries. <P>Under each of the families listed, the Compendium presents abstracts of all genealogical records pertaining to every individual of the surname, with the data deriving from primary record sources--marriage, birth/baptism, death, probate, land, military, pension, and census records. Systematically, under the heading of each of these record classes, it identifies every person of the surname of whom there is any mention in the records, then gives all relevant genealogical details (date, place, nature of event, etc.), and concludes with a precise citation to the source of the information. <P>To give the reader a visual representation of the various places mentioned in the text, each volume contains a map showing details of the five historic districts of the Mohawk Valley: Canajoharie, German Flats, Kingsland, Mohawk, and Palatine. Originally all this area was in Tryon County, then, from 1784, in Montgomery County.
