identify individuals but, because it is inherited, there are also regions of the
DNA strand which can relate an individual to his or her family (immediate and
extended), tribal group and even an entire population. Molecular Genealogy (宗谱学)

communities and populations which have lost precious records due to tragic
events such as the fire in the Irish courts during Civil War in 1921 or American
