Son of John Willcockson, Sr. and Sarah Boone. His birth year is estimated.
As a young man, Israel moved with his parents from North Carolina to Lexington, Fayette Co., KY. He does not appear to have married.
He owned 400 acres of land in April 1779, in Fayette, that he had planned to settle according to court record. After Israel's death, the land was deeded to Levi Todd.
Israel Wilcockson is listed as a Virginia Soldier in "Revolutionary Soldiers of Virginia," by Hamilton Jones Eckenrode, 1881, Virginia State Library, Archives Division.
Autumn of 1780, after the Bryans had left, just a few cabins at Bryan's Station were occupied.
Israel was killed in the Spring of 1781, at Bryan's Station. There are as many versions of this following story that place him at Bryan's Station, as there are those who told it. Here is one more.
Israel was sitting on a fence as the lookout for Indians, while observing his brother, (Lt.) Daniel "Wilcoxen," plow his cornfield just outside the fort. Israel was attacked and killed by Indians. Daniel fled for his life to the safety of the nearby fort. Some say his mother Sarah, some say his wife Sarah, shouted encouragement, as he made it to safety.
George W. Rank, in his book, page 22, "The Story of Bryan's Station . . ." as told in the Historical Address delivered at Bryan's Station, Aug. 18, 1896, did not know the identity of Israel Willcockson, "the lookout," who was killed in the Spring of 1781. He records a young man named Huttery Lee, who was also ambushed, killed and scalped June of 1781. Mr. Rank states that these two were buried "by the side of William Bryan in the rude station graveyard across the creek."
Dorothy Ford Wulfeck, M.A., author of "Willcockson and Allied Families," 1958, recorded the story, identifying Israel Willcockson as the lookout and brother of Daniel.
