Cosad became a successful farmer in Junius. After an eight-month hiatus to join the San Francisco gold rush (in which he was less successful), in 1851 he purchased 164 acres of farmland in the town of Huron, to which he added acreage and buildings through the years. He was active in local Republican politics.
An 1872 farm accident left him able to walk only “with crutch and cane.” He focused more intently on his interests in freethought. In 1875 he erected a meeting hall across from his residence for the specific purpose of holding freethought gatherings. His farm was thus an ideal setting for the area’s first freethinker meeting of regional, if not national, scope.
Cosad died in 1893. He is buried in the Cosad family plot in nearby Huron Evergreen Cemetery. His son, Samuel Cosad, attained prominence in local politics.
