Clay, Bruce, and Kavanaugh Families: Lineage Memorial – Revisited
by Charles von Dietrich Knighton and Patricia M Donaldson
This book traces descendants of three Colonial Virginia families who settled in Kentucky’s bluegrass region before 1800.

- Clay of the Old Dominion
Charles Clay, born 1645 in Charles City County, Virginia, died about May 1686 in Henrico County, Virginia. Notable descendants include Dr. Henry Clay (1736-1820) of Bourbon County, Kentucky, his double first cousin General Green Clay (1757-1826), and statesman Henry Clay (1777-1852). Dr. Henry Clay was the father of Elizabeth (Clay) Bruce (1755-1832), of the fifth generation. - Bruce of “Kentucke” County, Virginia
John Bruce was born 30 April 1748 in Virginia, the son of an exiled Highland Scot. He was a Revolutionary War soldier who took up land in what are now Garrard and Lewis Counties in Kentucky, where the family prospered. His numerous descendants include Horatio Gates Bruce (1793-1858), lawyer, and Kentucky State Legislator, Sophia (Bruce) Palmer (c. 1782-1818), and her daughter, Margaret (Palmer) Kavanaugh (1812-1860). Lt. General Andrew Davis Bruce (1894-1969), first chancellor of the University of Houston, Texas, was of the fifth generation. - Kavanaugh of the Old South
Philemon Kavanaugh, born about 1690 to Irish exiles, died in the Colony of Virginia before August, 1744. Philemon’s descendants by his two wives include Philemon (b. 1754) of Culpeper County who was killed by Indians in Montgomery County, Virginia, in 1779 for his red hair; Hubbard Hinde Kavanaugh (1802-1884), Bishop in the Methodist Episcopal Church South. Sophia Elizabeth (Kavanaugh) Bear, born 1830 in Garrard County, Kentucky, died 1871 Jefferson County, Indiana, was of the sixth generation.
