< The brutal axe murder and dismemberment of a Negro slave, committed in 1811 by two brothers, Lilburne and Isham Lewis, whose mother was Thomas Jefferson?s sister and whose father was his first cousin, form the core of this historical detective story and account of frontier life in western Kentucky in the first decades of the nineteenth century.
On the night of December 15, 1811, drunk and enraged over the breaking of a pitcher, Lilburne bound his seventeen-year-old slave, George, and, in front of the assembled household?s other slaves, cut off his head. The brothers were indicted for murder, released on bail, and attempted suicide.
Boynton Merrill Jr. explores the tragic combination of circumstances and social forces that culminated in this ghastly event: the lawlessness of the frontier settlements, the dehumanizing effects of chattel slavery, and the Lewis family?s history of mental instability and their ever-declining fortunes.>

<The Anchorage is a substantial farmhouse which evolved over half a century beginning possibly as early as 1826. The property was owned first by the Lewis family, for some 20 years by the Howell Lewis family, and then for more than a century and a quarter by John White and his descendants. The Whites were prominent farmers and citizens. The house is characterized by impressive Victorian embellishments including Gothic Revival interior woodwork, elaborate porches with scroll-sawn ornament, highly original Italianate octagonal columns, and both real and false windows enriched with elaborate wooden pediments resting on brackets. The house sits in a bucolic setting that includes a barn and family cemetery, both contributing resources, in the midst of rolling fields surrounded by hills and mountain vistas. The property is eligible under Criterion C in the area of architecture for the unusual character of its architectural finishes and the high degree of integrity of its evolved form. It is a key element of a group of related area buildings that merit additional study. >
Thinking out loud. JMO of course.
