A biographical sketch of Robert Allan's nephew James, provided at WorldConnect by CarolWilk@aol.com (Carol Wilkerson):
James ALLEN II (Sr.)
Death: 4 JAN 1811 in Danville, KY
As a child he had come to America from Ireland with his widowed mother, and arrived in Pennsylvania. Here she lost all of her money in a fraudulent land scheme. So, penniless, they moved to Botetourt County, Virginia. After they had secured a home and were thriving, young James went to the West Indies in search of his fortune, and there he spent his early manhood and had great sucess. He returned to Botetourt County, and married Mary Kelsay. In 1779 they left Virginia and went by wagon over trails used by hunters into Kentucky, where they settled in the wilderness away from other settlements for three years in the midst of constant danger and Indian warfare. He and a friend built the first cabins outside of a fort (near present day Danville, Kentucky). In 1784, James bought a large section of land (in what was to later become Nelson County) and built upon it a comfortable home. He returned for his family, and upon bringing them to their new home they found it in ashes as well as the nearby fort, burned to the ground by Indians. He then proceeded to build a new home on the same site, where they lived for the remainder of their days. Mary died there on May 14, 1808, and James died there January 4, 1811. It was written of James that "he lived to an extreme old age, in the midst of broad acres his rifle had helped to redeem from the Indians, in which had been converted by his labor from a wild canebrake into a blooming and fruitful garden." Of their six children, three sons and son-in-law placed themselves forever in the history of Kentucky. Allen County was named in honor of their son, Colonel John Allen. Descendents were to be governors, lawyers, soldiers and duelists.
