Which I guess raises the question: how do the Jesuits feel about the various groups of Corsicans, high and low, and including the Greeks and the Jews?
Broadly speaking, it depends on the Jesuit. The exiles are from all over the Spanish Empire, and as a consequence they come from a wide variety of different backgrounds and lived very different lives. Even among the American Jesuits there were many different experiences - The Jesuit who has spent his career on the distant frontiers of Spanish America, reinforcing the Catholic faith and instructing the natives in agriculture at a mission or reduction, probably has a different worldview than a Jesuit who lived in a big colonial city educating the
criollo urban elite. Some Jesuits will undoubtedly be scandalized by the "backwardness" of the country, its rather unorthodox religious practices, and the total lack of urban sophistication; some may be accustomed to the rural simplicity of the frontier and the superstitious heterodoxy of the Indian peasantry and will take no offense.
Antonio López de Priego, whom I quoted in the update, doesn't have many nice things to say about the people or the island. Priego's account reads like the world's worst Tripadvisor review - the towns are poor and ugly, the people are surly and aggressive, porters are constantly trying to gouge him or steal his luggage, and nobody knows how to speak properly (the Corsican dialect is unintelligible to him, and at one point he says it "seemed to be Otomi," a native language of central Mexico). It's worth remembering, however, the circumstances in which he arrived and the state of Corsica at this point in history. The Spanish officials spared nobody, deporting even the sick and aged, so there were a lot of infirm priests who simply died on the long journey. When they eventually reached Corsica they still couldn't disembark, because the island was presently at war; they spent months confined to crowded ships in the middle of the Mediterranean summer, causing many more deaths. When they were finally allowed to land they were herded into various barracks and camps across the country, but because there wasn't enough space for them many were quartered in stables, ruins, or houses recently vacated by Corsicans who had fled into the interior. They feared getting caught in the crossfire, and most of all they feared the French, who drove the Jesuits out of the territory they controlled and treated them with hostility and contempt. Because the country was in turmoil and ill-equipped to handle such an influx of population, food was hard to find, and when it could be found it was extraordinarily expensive. Even with some outside help, their existence was highly precarious. Many of the Jesuits endured these conditions for more than a year. As they suffered through all this, the American-born Jesuits could also contemplate the fact that they had been exiled to the other side of the world and would probably never see their homeland or their families again, as even
ex-Jesuits were forbidden from returning to Spanish territory.
Sometimes it's hard to separate Priego's opinions of the Corsicans from the misery of his own experience. Take this passage:
We delayed there [Ajaccio] one day, and some of us went ashore to see the cathedral and to visit the Blessed Sacrament. But, on beholding this new world, we were astounded and could only gaze at each other, without uttering a single word: women with their legs crossed were seated in the pews; bearded men were seated in the confessionals, and, clerics wearing their capes, kept marching back and forth from the choir to the cemetery, as if engaged in a ludicrous performance out on the public plaza. Some of our religious that had arrived previously were living under the staircase, others in the kitchen and still others in the stable. On beholding all this I was deeply pained, and, leaving there, I did not go ashore again until we reached Bastia...
What pained Priego more, women crossing their legs in church or the fact that his poor brothers were literally sleeping under the staircase? If he and his comrades hadn't been so miserably treated, would he have given a more charitable account of the country?
Corsica is not a paradise, but its situation ITTL is much better than IOTL. Corsica's government doesn't have a lot of resources, but it is stable. The people aren't wealthy, but at least they're not desperate survivors in a war-torn land. The Jesuits aren't living in lavish conditions, but neither are they being herded into detention centers, sleeping rough in tumbled ruins, chased about by French troops, or just ignored by everyone and left to starve. Thanks to Corso-Spanish negotiations they're even receiving a modest stipend, which IOTL they didn't receive until 1769 when they finally made it to Papal territory. Maybe Priego will still have unkind things to say, but one hopes the willingness of the Corsican government to take the Jesuits in - and, after 1770, to ignore the official dissolution and allow the Society to still exist - would have some effect on his attitudes and those of his comrades.
