My name is A. Gil de Lamadrid in San Juan. I read your message regarding the Gil family. From what I have been able to find out, the Gil family came from Santander, Spain - they adopted the place where they resided - Lamadrid, thus becoming Gil de Lamadrid. I have been able to trace my family in Puerto Rico back to Arecibo in the mid - to - late 1800s.
