I have a listing of Early Immigrant Ancestors which lists a George Hume (1698-1760) who was a son of Sir George, the 9th Baron Wedderburn, Scotland and descended from King Robert Bruce, King Malcolm II, and Edward the Elder. George came to America from Scotland , was a surveyor for William and Mary College in 1727-1729, and for Augusta, Spotsylvania, Orange and Culpepper Counties, and laid out the city of Fredericksburg, VA. Officer in the Colonial Wars. Married 1728 to Elizabeth Procter who was born 1700 of VA.
COuld this be the brother to Barbara's father James, and brother to the historian David Hume (07 May 1711-1776)??
This book also lists William Hoge (1660-1750) from SCotland circa 1682 settled at Perth Amboy, NJ. He was the founder of Washington Co, PA and settled finally at Opequon VA. Married to Barbara HUme (1670-1745).
