True. People down there know where they came from, but apart from the tourist business, it's a little like Dutch or the Huguenots or the Scots in New York or South Carolina or North Carolina. Not exactly like that because it happened more recently, but they're Brazilians and they aren't looking to restore the Confederacy.
If anything it would appear that people are trying to keep the story alive.
I’ve found similar news stories (since archived) that were covered here over the years:
