From The Arizona Daily Star comes this little story about Olson's family tree:
"Lute Olson's great-grandfather was a Norwegian farmer named Ole Anderson. Ole Anderson's son - Lute's grandfather - also was a farmer who moved to North Dakota from Norway alone at age 19. Vebjorn Olson took his last name from an old Scandinavian tradition of patronymics, wherein sons took their fathers' first names and added 'son.' "
Incredible resources are available online and through the LDS church - and it's addictive detective work once you get started tracking down your ancestors. Coach Pukerud just doesn't sound the same, though.
