In the mid to late 1800s the British changed the way the spoke their language. In their never ending goal to stratify their society and separate the lower class from the betters British schools began teaching students to speak differently for the commoners. The way most Brits would have sounded in 1800 is much closer to how a kid form Virginia would speak than how a kid from London would speak.

And sorry including the dialect of non-native English speaker Really isn't valid. While some of the speak English great many speak a very broken English and use none standard structure. According to the arbitrator of all debated on the internet only about 5-8 percent of India are considered fluent in English so if I was to give you them you still are wrong.
