Several of Kennan's forebears were ministers, including patriarch Thomas Kennan, a Presbyterian-Congregationalist pastor in the early 19th century. Kennan explores the tensions between conservative and liberal Presbyterian tendencies in the context of the Great Awakening, and the revivalist waves that swept frontier areas. He shows the importance of churches in knitting together the transitory settlements of early America and the central role of ministers and religious denominations in organizing education from the grammar schools through college. "An American Family" offers an absorbing study of the role of religion in New England society, a legacy that still constitutes the bedrock of American identity.
