The manor house was built in a strategic location of the former carretera real or military road (today PR-2) that connected Hormigueros and Mayagüez to San Germán, the largest town in the region at the time.

The former slave workforce was hired by María Margarita, who became the sole owner of the hacienda until her death in 1885, when the plantation and house were bought by María Luisa del Carmen Capurro Marchany and her husband Narciso Deulofeu Serra, a newly arrived immigrant from Catalonia.

During this time the hacienda also diversified its agricultural production to coffee, cotton and other important edible crops in order to expand its industrial output.

[1][3] A large portion of Hacienda Valentina, the name given to the property during the time, was expropriated in 1892 during the construction of the railway and the Hormigueros station.

Despite the closure of the hacienda, the manor house became an important architectural, historical and cultural landmark in Hormigueros.
