Not all black people are African-American though. There is a very large Nigerian population in the area. If you didn't know, Nigeria was of the main exporters of slaves during the trans-Atlantic slave trade. Much of their wealth was built off the back of slaves, so I doubt they care if it is called Dudley Square. Even in Lagos—Nigeria's largest city—there is Tinubu Square, named after a famous slave trader. There is even a statue of her there. Ironically, it was originally called independence square.
