I'll have to do some image on it also, to see it good. I came across some info, in reading from old research material, there was a later Spanish Plate Fleet got caught in a hurricane and lost 5 ships in the area of the land grant document you posted. I'm not including the date yet of the fleet, because I googled it and found nothing. First want to go back and check the date. It happened in October of that year, 5 ships wrecked in or near Pensacola Bay but is supposed to be in another bay which name doesn't google either.
