 Many residents claim Irish ancestry because of known "Scots-Irish" among their ancestors, who immigrated from Ireland, where their ancestors had moved for a period from Scotland during the plantation period.As of the 1980s, the only counties in the United States where over half of the population cited "English" as their only ancestry group were in the hills of eastern Kentucky (virtually every county in this region had a majority of residents identifying as exclusively English in ancestry).The Ridgetop Shawnee organized in the early 21st century as a non-profit to gain structure for their community and increase awareness of Native Americans in Kentucky.
