Drawing on newly translated materials and previously overlooked primary sources, Randolph Paul Runyon explores the life and times of the important but understudied pair in this intriguing dual biography. He illustrates how the Mentelles’ origins and education gave them access to the higher strata of Bluegrass society even as their views on religion, politics, and culture kept them from feeling at home in America. They were intimates of statesman Henry Clay, and one of their daughters married into the Clay family, but like other immigrant families in the region, they struggled to survive.
