Looking for my relatives the Tiburcio Giron family from San Elizario/Tigua there were 3-4 Tiburcios in that family. I believe the 2nd one was married to a Maria Curan Giron. The last Tiburcio Giron was born on 7-15-1904 and passed away in March of 1985. One of the Tiburcios was married to an Isabel and also had a daughter named Isabel Giron ( who married a Leonardo Escobar).
I believe they are related to the people of the Hacienda Tiburcios founded in 1730-50 it was the forerunner of San Elizario.
