DNA testing will not replace the more familiar genealogical research
techniques of gathering oral and documentary evidence and compiling family
trees. Instead it offers entirely new research tools - more information to
augment the documents and oral histories - as well as a way of testing family
trees, to see if conclusions drawn are confirmed by this new evidence. This book
shows you how you can use DNA to harness this exciting new range of genealogical
The amount of scientific jargon associated with genetics can be intimidating.
This publication provides a contextual understanding of DNA suitable for
genealogists and discusses the currently available tests that are likely to be
of interest to family historians, especially those wanting to prove (or
disprove) compiled family trees, the connect 'new' relatives by means of
inherited genetic material and to draw conclusions about where we fit into the
greater human family.
