Among the first immigrants was Dr. Nunis, who was made welcome because of his medical knowledge, and because he, with a number of others, brought sufficient wealth to the colony to enable the immigrants to take up large tracts of land. A congregation was organized as early as 1734. Three years later Abraham de Lyon, who had been a "vigneron" in Portugal, introduced the culture of grapes. The cultivation and manufacture of silk and the pursuit of agriculture and of commerce were the chief occupations of these early settlers. A dispute with the trustees of the colony respecting the introduction of slaves caused an extensive emigration to South Carolina in 1741, and resulted in the dissolution of the congregation. But in 1751 a number of Jews returned to Georgia, and in the same year the trustees sent over Joseph Ottolenghi to superintend the somewhat extensive silk-industry in the colony. Ottolenghi soon attained prominence in the political life of his associates, and was elected a member of the Assembly in 1761 and in succeeding years. There seems to have been little if any distinction made socially between the Jews and the other settlers, and educational and philanthropic institutions seem to have been supported by all alike.
