I want to know the answer to the following question:
When was the Bronx added to?
All the background I'm provided with is that "The name for this region, apparently after the Bronx River, first appeared in the Annexed District of the Bronx created in 1874 out of part of Westchester County and was continued in the Borough of the Bronx, which included a larger annexation from Westchester County in 1898.". Is that enough to answer the question?
