Fratie Pearl Lilly Epling-Wyatt (1899-1977), Mercer County, West Virginia
Pearl's family who brought it to the West Virginia project thought it might have been made in the 1950s but I wouldn't be surprised to find it from the 1960s or early '70s, when many these snakes of double arcs were fashionable.
It is an unusual pattern, a variation of the double fan or snake.

It must have been a commercial pattern as these similar quilts from ebay show
