There was a historian in Tampa who published a bio on him (just one page) and in that bio he may be buried there. Never have been able to find any evidence of that. The info you provided is all spot on. It's the same Gregorio and Donato did return to St. Augustine after Gregorio died. They were also sons of Cristobal and Josefa Femanias. Thanks for all the info. That will be very helpful I'm sure! Eldridge Bravo
