After leaving Michigan State, Kirk returned to his ancestral home in Mecosta, Michigan, where he wrote the many books, academic articles, lectures, and the syndicated newspaper column (which ran for 13 years) by which he exerted his influence on American politics and intellectual life. In 1963, Kirk converted to Catholicism and married Annette Courtemanche, now named Annette Kirk; they had four daughters. She and Kirk became known for their hospitality, welcoming many political, philosophical, and literary figures in their Mecosta house (known as "Piety Hill"), and giving shelter to political refugees, hoboes, and others. Their home became the site of a sort of seminar on conservative thought for university students. Piety Hill now houses the Russell Kirk Center for Cultural Renewal. After his conversion to Catholicism Kirk was a founding board member of Una Voce America.
