From 1766 to 1832, Doughoregan Manor was the country home of Charles Carroll of Carrollton, last surviving signer of the Declaration of Independence. He lies buried in the chapel attached to the north end of the mansion. "Doughoregan" was a family estate in Ireland.
Members of the Carroll family still own and live in the manor, which sits at the center of a thousand acre (4 km²) estate. Recently a family member observed, "Only God, the Indians and the Carrolls have owned this land." The estate and Manor Lane are closed to the public.
