Let's see if I can still do this without peeking.
National League in the 50s, before Californization:
Philadelphia Phillies
New York Giants
Brooklyn Dodgers
Pittsburgh Pirates
Boston Braves
Chicago Cubs
St. Louis Cardinals
Cincinnati Reds (became Redlegs with McCarthyism, then back to Reds)

American League in the 50s:
Boston Red Sox
New York Yankees
Philadelphia Athletics
Baltimore Orioles
Washington Senators
Chicago White Sox
Cleveland Indians
Detroit Tigers

In 1957 or thereabouts, the Giants moved to San Francisco and the Dodgers moved to Los Angeles. Somewhere around the same time (I might be wrong on the time) the Athletics moved to Kansas City and the Braves moved to Milwaukee. In 1962, the National League added the New York Mets and the Houston Colt .45's (who became the Astros when they moved into the Astrodome), and the American League added the Los Angeles Angels (who became the California Angels when they moved to Anaheim, and then the Anaheim Angels when they were bought by Disney), and the Minnesota Twins. After that, things got really confusing.

And Anaheim was founded by German immigrants in the 1840s or 50s as a winemaking center, but they switched to oranges after the vines died. The name comes from the Santa Ana River and heim, German for "home".

Aren't you glad you asked?
