This may seem like a strange question but I was curious if there was any religious significance to this. Possibly, Jews following the opinion of a Rabbi who saw the name as signifying a place of belonging or a place related to Jewish symbolism. Thus, Jews started showing up in Brooklyn partly because they associated it with the Jewish faith.
The "Crown" or the Keter is typically spoken in relation to Kabbalah and the Sefirot. The Keter happens to be the top most point of the tree of life.
The "Crown" relates to the idea of the Mashiach and how they will eventually come and reestablish the Davidic royal line.
The "Crown" relates to Hashem and how we identify him as one would identify a king. We are not only taught to give Hashem the respect we would as one does a King, we refer to him as "King" of the universe.
It just seems to me that it makes sense from a religious standpoint that the Jewish people would gather in a place that can symbolically reflect different Jewish themes. That seems like more than just a coincidence to me.
I was curious if this is a verified idea or not.
