Hey I think I can shed some light on your search and me coming across this post I can connect some of the dots already. My family as well are from Santiago de los cabaelleros ,Dominican republic but we are from a pueblo called navarette .I spoke to my father today and he gave me a quick recap of his knowledge on the Batista name ...his name is Jose Rosendo Batista his fathers name my grandfather is called Cesar Batista and his fathers name is florencio Batista,now I can see that your middle name is florencio so I'm guessing florencio was an important figure to the batista family if you have that name as your middle name I'm guessing you have other florencios in your family .As in how Batisa migrated to Santiago my father told me when the batistas first got to DR they really landed in La vega and after my granfather was born my side of the family moved to navarette .I hope the information I provided can help in your search as well as for me any type of info would be appreciated . if you wish to contact me just email me any time. guy830@gmail.com
