The Dictionary of American Regional English (paywall) has a listing of "sirsee" (variously spelled "circe," "circi," "surcy"). East and South east U.S.: NC, SC, GA, and PA, as well as two reports from Buffalo, NY and Oklahoma. The etymology is uncertain, but one plausible source is the Scot/Irish verb "sussie," meaning "to take trouble, to care, to bother oneself."
