The Campbell DNA Project was launched in October of 2002 with the purpose of trying to help genealogy researchers break through brick walls. The goal of the project was to attempt to get DNA samples of several Campbell reference lineages and to look at opportunities to link current genealogy research to these lines.
From elementary genetics we learn that the Y-chromosome is passed down through the male line, essentially unchanged, from generation to generation. These chromosomes "mutate" or change slowly over time allowing identification of specific families and surnames. The rate of change is extremely slow, being measured in terms of tens or hundreds of generations. The reader might want to read an excellent article about the Y-chromosome written by Dr. Mark Jobling of Leicester University entitled "". Additional articles and journals have reported the examination of the STRs (Short-Tandem Repeats) on the Y-chromosome to trace and analyze surnames. A well-publicized case involved the question as to whether or not President Thomas Jefferson fathered any slave children by Sally Hemings.
Many other articles such as "" by Dr. Neil Bradman and Dr. Mark Thomas as well as a review article by Dr. Mark Jobling entitled "", volume 17 of Trends in Genetics are worth reading for background information as they deal with this specific subject. There are many web sites now dedicated to this subject that provide links to many excellent articles and the results from other surname projects. Thus, it has been well demonstrated through university research that an analysis of the male Y-chromosome can be used to trace the male descendants of a progenitor through many generations, all of which share a common surname.
