What are the possibilities of "Boer" societies popping up in other parts of the British Empire? that is to say Dutch speaking colonists who lose their colony to the British Empire But retain a separate identity to the modern day and resent the British. It is also required that a large portion of these Dutch have a version of the Great Trek to avoid British rule.
This of course challenging since it requires a larger Dutch presence before a British takeover, I believe Australia might be a candidate if say a small settlement was stranded because their ship ran aground the reefs, the group manages grow somewhere near Queensland. Because the settlement is fairly inaccessible and British colonisation began in New South Wales, the Dutch are left to grow for a long period in isolation. Eventually British come and rather than lose their independence some Dutch retreat to the Outback to form independent "Boer Republics".
Is this plausible?
