"house" female (housekeeper, maid, cook, laundress, or nanny) to be raped by one or more members of the household. Houses of prostitution throughout the slave states were largely staffed by female slaves providing sexual services, to their owners' profit. There were a small number of free black females engaged in prostitution, or concubinage, especially in New Orleans. Slave owners who engaged in sexual activity with female slaves "were often the elite of the community. They had little need to worry about public scorn." These relationships "appear to have been tolerated and in some cases even quietly accepted." "Southern women... do not trouble themselves about it". Franklin and Armfield, who were definitely the elite of the community, joked frequently in their letters about the black women and girls that they were raping. It never occurred to them that there was anything wrong in what they were doing. Light-skinned young girls were sold openly for sexual use; their price was much higher than that of a field hand. Special markets for the fancy girl trade existed in New Orleans and Lexington, Kentucky. Historian Philip Shaw describes an occasion when Abraham Lincoln and Allen Gentry witnessed such sales in New Orleans in 1828: Those girls who were "considered educated and refined, were purchased by the wealthiest clients, usually plantation owners, to become personal sexual companions". "There was a great demand in New Orleans for 'fancy girls'." The issue which did come up frequently was the threat of sexual intercourse between black males and white females. Just as the black women were perceived as having "a trace of Africa, that supposedly incited passion and sexual wantonness", the men were perceived as savages, unable to control their lust, given an opportunity. Another approach to the question was offered by Quaker and Florida planter Zephaniah Kingsley, Jr. He advocated, and personally practiced, deliberate racial mixing through marriage, as part of his proposed solution to the slavery issue: racial integration, called "amalgamation" at the time. In an 1829 Treatise, he stated that mixed-race people were healthier and often more beautiful, that interracial sex was hygienic, and slavery made it convenient. Because of these views, tolerated in Spanish Florida, he found it impossible to remain long in Territorial Florida, and moved with his slaves and multiple wives to a plantation, Mayorasgo de Koka, in Haiti (now in the Dominican Republic). There were many others who less flagrantly practiced
