The first settlers arrived on the island by the end of the second quarter of the 15th century. The expansion of settlement occurred after initiatives by the island's third donatary captain, Rui Gonçalves da Câmara (son of João Gonçalves Zarco, resulting in northern colonies from peoples from Madeira. Although the early settlement of Ribeira Grande is mired in murkiness owing to the lack of resources, the best sources indicate that settlement began in the late-15th or early-16th centuries. The first settlers to this region are to the northern part of the island by the end of the 15th century. On arriving, these colonists established their settlement along the ravine, which they eventually named after the river course: Ribeira Grande. What is certain is that before 1507, in the urban areas of today's Ribeira Grande, there were already colonists of a "certain social stature" living and raising cattle. One of these was Antão Rodrigues da Câmara, the bastard son Rui Gonçalves da Câmara, donatary-captain of São Miguel. His parentage was legitimized on 6 January 1499, and his property (situated in Ribeirinha) was described as an estate, with lands of woodlands, pasture and waters, with houses supported by granaries, haylofts, pastel engine, vineyards and orchards, received as part of his "morgadia" dated 17 April 1508.
