What is genealogy? Historical origins

The Old Testament contains many examples of family registers.
Descent among European nobility was of great importance for the inheritance of titles and the use of a family-'s coat-of-arms. Great emphasis was placed on the ancestry and bloodlines of a couple wishing to marry.
