The following is not about genealogy, but about some contemporary (i.e., 20th century) Mexican culture.
The Smithsonian's National Museum of American History (NMAH), in Washington, DC, has undergone some extensive renovation and is scheduled to re-open on Nov 21. The section on Popular Culture will now be called "Thanks For the Memories", and one of the exhibits will feature "Cantinflas". Those of you of a certain age may remember a Mexican comedian named Cantinflas who appeared in many Mexican films, mostly in the '40's and '50's, and also appeared in the US film "Around the World in 80 Days".
