I would not have cared to travel on that particular ship BUT I am sure they dined well.
There were thousands of private ventures that were never reported and show no evidence here of ever having happened, but there are some extensive reports about some of them.
I suspect the death rates were spectacular for those 16th century voyages ~ but you would have had people coming from every Hapsburg land ~ so they were already here to some extent when your more familiar Brits and French arrived.
As a side venture in looking for these earlier settlements I've been looking for practical connections between the Swedes and the Spanish and there do seem to be "such events" and business deals. I guess they were just too far apart to cause each other trouble, but the Swedes were a house afire in pursuing improvements in common technology ~ better boats, better firearms, better steel, better armor, better machines ~ new designs.
As the Spaniards found out America was a huge place and it took everything they could to do anything at all.
The far interior Spanish fort in NC was burned by Indians in 1568, according to Spanish records. This would have been Joara in native parlance or Fort San Juan, established by Juan Pardo, really more of a garrison with thirty or so soldiers and held for less than two years. Seems to have been a coordinated attempt to drive out the Spanish, as forts in SC and TN were burned that same year as well.
