In the late 18th or early 19th century a group of runaway slaves and serfs fled from Kentucky into the Ohio Territory, where they inter-married with Natives and formed a tribe - red, white & black - called the Ben Ishmael tribe. The Ishmaels (who seem to have been Islamically inclined) followed an annual nomadic route through the territory, hunting & fishing, and finding work as tinkers and minstrels. They were polygamists, and drank no alcohol. Every winter they returned to their original settlement, where a village had grown.
But eventually the US Govt. opened the Territory to settlement, and the ~official~ pioneers arrived. Around the Ishmael village a town began to spring up, called Cincinnati. Soon it was a big city. But Ishmael village was still there, engulfed & surrounded by "civilization." Now it was a ~slum~.
