I want to know the answer to the following question:
What year did the Chicago Cubs' name become official?
All the background I'm provided with is that "Officially, the Cubs are tied for the distinction of being the oldest currently active U.S. professional sports club, along with the Atlanta Braves, which also began play in the NL in 1876 as the Boston Red Stockings (Major League Baseball does not officially recognize the National Association of Professional Base Ball Players as a major league.)". Is that enough to answer the question?
Answer: no
