Hi, Greg. This is Luz. There is much info on
the Betancourt family. Mine is from the Canary Islands of Spain. They, theoretically, can be traced back to Jean Betancourt of Granville, in Normanday, France. They migrated to Puerto Rico, where my family is from,probably in the early to mid 1800's. also to Cuba, New Orleans in the USA, and to parts of South America.
At this point in time, there are many Betancourts in the USA.
Feel free to get in touch if you need further info.
