This is so exciting to those of us who are tracing our ancestry with roots in Hungary!
A majority of Hungarian-Americans today can trace to the immigrations of the Industrial Revolution. We find ancestors on US census (and some state census) in 1890, 1900, 1910, 1920, 1930, and now 1940. They have lived through the Great Depression and are will be involved in World War II. These other census are not available as digitalized images at the National Archives site, which is accessible anywhere there is an Internet Computer.
