Genetics and geneology Genetics and geneology rescue our ancestors from oblivion Quite a few people like to know who their ancestors are. Most of my students know their grandparents but have no clue about great-grandparents or earlier relatives.
Some people look for their relatives through genealogical libraries.
The best is in Salt Lake City run by the Mormons. It was free. It was fun getting information on the size of families of my ancestors and their birth orders. In Sweden King Gustavus Vasa ordered a catechism test every five years for every Swede. I even saw how my relatives did on their examination about 200 or more years ago.
