Most likely Brazil, but they would not last long, their best case scenario is to have the USA to pardon them in the late 19th century and so they move back to the USA
In the worst case scenario the brazilian government returns them back to the US immediately and they are arrested
The most likely is that they would remain as the unrecognized government in exile for some time (this could be a good movie) until they drop the idea in the 1880s and settle down here
