We may be related. My grandparents, mother side,from Puerto Rico: Pedro Pablo Bonilla Mas, born 1871 and from Dominican Republic: Carmela Atiles, born 1872. They lived in Ponce, PR for a couple of years and moved to Dominican Rep. Pedro Pablo's father was Jose Antonio Bonilla España married Isabel Mas. No more data. Looks to me that Pablo, your grandfather may be a nephew to Jose Antonio. I suggest you contact PR Genealog. Society.
