My family is from Lajas, PR. It is my understanding that most of the Toro people come from the southwest part of the island.
A friend of mine from Ponce did a Toro ancestry search (for a school project) and found that the Toro name got to PR with three brothers. The all settled between Mayaquez and Ponce. It seems to make sense since all Toro's from PR are within that area.
Also, I find it interesting that the name Toro is not popular in New York. I never went to school or met a Toro in NYC that was not related to me (except for the Toro I met from Ponce).
I am very proud of the Toro name and love visiting my hundreds of relatives (mostly Toros) in Lajas PR.
