Looking for Connell Mccadden Washington County PA

Born 1745-1750 in Ireland, was in Adams County, PA from 1800 to 1830 when he appears in the 1830 US Census in Fallowfield Twp., Washington County, PA. Can't be found in 1840 Census so probably died before 1840. Was Catholic, so probably buried in a Catholic Cemetery, Washington County. Does anyone have such Cemetery records and can find him?
