Laura Ingalls Wilder had only one child who survived to adulthood, Rose Wilder Lane. Rose had only one child, who was stillborn. Laura Ingalls Wilder has no living direct descendants, and neither does her father, Charles Ingalls. Perhaps your classmate descends from one of Laura's cousins.
Not sure why Lindbergh is on a Missouri quiz - he was born in Michigan, graduated from high school in Minnesota, was based in St Louis when he flew Air Mail for the Post Office. The financial backers for his flight were from St Louis, but the plane was built in San Diego and flew from New York to Paris. If he had flown an Apache helicopter, could he claim to be Native American?
