(Worth SGC) REFERENCES Bushnell, Amy Turner 1978. The Menendez Marquez cattle barony at La Chua and the determinants of economic expansion in seventeenth-century Florida. Florida Hist. Q. 56: 407-431. "The most imporant of the 17th century cattle ranches was the hacienda de la chua ("ranch of the sinkhole" in north-centeral Florida, operated by the Menendez Marques family, who were related to Pedro Menendez de Aviles himself. The earliest possible date for their ranch is 1646, 81 years after the founding of St. Augustine; the first reference to its exports is in 1675, and to its name, 1682. If large-scale ranching could take this long to get started the reasons must be significant."
