In the wake of highly-publicized scientific breakthroughs in using genetics to establish family connections, genealogists began to see potential for their own research. Now many are finding that organizing tests is a relatively straightforward matter - and that comparing the DNA signatures of individuals can reveal startling information on families, surnames and origins. Here Chris Pomery explains the practicalities of testing and interpreting the results. He also takes an objective look at the issues. Whether you are simply seeking to stay informed, actively interested in exploiting the technology, or already part of a DNA project, this is the one guide that fully explores the existing possibilities. Chris Pomery is organizer of the pioneering Pomeroy study, which has been widely cited in coverage including Radio 4's Surnames, Genes and Genealogy and Steve Jones' controversial book Y: The Descent of Men. He lives in Cornwall, England.
