Thank you, I enjoyed your research thoroughly.
I guess with a name like ‘Virginia’ - a name which does, originally, come from QE1 - it’s hard to ascertain whether the name is after the person or the state that’s named after the person, unless we can find a direct link back to the state (such as, as per your example, a former Governor or perhaps a land owner with connections to the state).
There also seems to be a sector named after islands of the West Indies, and another with Australian places - e.g. Our Lady of Lourdes Catholic Church is located in a quadrant defined by Murray Road, Sydney Place, Canberra Drive, and Melbourne Ave.
To go off the topic a little, is there anywhere in any country with as many streets being given as many names used nowhere else as Columbia, Maryland, which was established in 1967? It’s split into ten villages, and each village is split into several neighborhoods. There are a total of thirty neighborhoods. Each neighborhood has all of its streets named from a single artistic/literary source (I think). So there are neighborhoods named after things from Tolkien, from Twain, from Whistler, from Frost, from Dickinson, and from American folk songs, for instance. I can’t find any list online of all the sources, but there’s a book called Oh, You Must Live in Columbia! which explains the origins of all the names, but the text of the book isn’t available online (I think).
Maryland Point is a district in east London, originally the estate of merchant Richard Lee, who made his money in the USA. It was named after Maryland Point on the Potomac River.
Fun fact: Richard Lee was the great-great-grandfather of Robert E Lee.
