According to José Ferreras Pagán 1902 book Biografía de las Riquezas de Puerto Rico, Hacienda Luisa Josefa was originally owned by Carlos Fajardo Belvis (1822-1890) whose descendants established the nearby Central Eureka.  Carlos Fajardo Belvis and his first cousin and wife Maria Luisa Cardona Belvis, were registedered owners in 1867.   

Although Carlos Fajardo Belvis was at one time owner of Hacieda Luisa Josefa, according to the history of the town of Hormigueros, the first sugar factory in the municipality of Hormigueros was Hacienda San José, established ca. 1827 by Mateo Belvis Taveyra (1759-1832) and his wife Maria Antonia Garcia.  Hacienda San José was later the basis of Central Eureka.

Mateo's daughter Manuela Belvis Garcia and her husband José Antonio Antonio Ruiz Gandia (1810-1868) followed by establishing Hacienda Luisa Josefa where their son, attorney, politician and abolitionist Segundo Ruiz Belvis (1829-1867) was born.  Segundo freed several of Hacienda Luisa Josefa's slaves in 1866 before he was exiled because of his political views and seven years before the abolition of slavery in 1873.  In 1867 Hacienda Luisa Josefa was, as stated above, owned by Segundos' cousin Carlos Fajardo Belvis, the son of Maria de Jesús Belvis Garcia, sister of Segundos' mother Manuela Belvis Garcia.    

Ferreras Pagán states Hacienda Luisa Josefa's ownership passed from Carlos Fajardo Belvis to Latimer & Co., then to Eduardo Kemp of New York and then to José Antonio Gonzalez Echevarria (1832- ) and Spanish immigrant from Andalucia Damián Del Moral Carmona (1848-1904) who were its owners in 1902.  The 1872 Slave Register shows José Antonio Gonzalez and the firm Gonzalez Echevarria Hnos. with five slaves registered in Barrio Candelaria of Mayagüez and the 1910 Census shows José Antonio Gonzalez Echevarria as a coffee farmer residing in Barrio Sabalos of Mayagüez.  It is reasonable to believe Latimer & Cia. and Eduardo Kemp acquired ownership either by foreclosure or in lieu of payment as one of Latimer & Cia. principal businesses was crop financing. 

The Governor of Puerto Rico Report to Congress dated December 17, 1923 states that a water right was granted to Carmen Josefa Defilló Gonzalez to extract 40.71 lites per second from the Duey Alto River for irrigation of 197.78 acres of land of Hacienda Luisa Josefa.  It appears the correct owners should have been sisters Carmen Defilló Gonzalez (1864-1954) and Josefa Defilló Gonzalez (1869-1955).  It is unknown to us at this time how ownership was transferred to the Defillo sisters.

This facebook page states the ruins date from 1870 and are from the area where agricultural products were washed.  It states that waste water was channeled from the wash tank to the nearby Hoconuco River.  The Guanajibo River, Hoconuco River and Duey River meandered through the hacienda's three hundred four acres which were part in the municipality of Hormigueros and part in the municipality of San Germán.  ​

The ruins below are located in Barrio Benavente of Hormigueros, south of what is today today PR-2 which then was the trail from Barrio Duey Bajo to San Germán.  Its lands appear to abutt to those of Hacienda Filial Amor to the south.
