Full Family in West Virginia

In the book "The History of Wood County, West Virginia, 1980", under the "Sheppard Family" it states that "Samuel Sheppard 1803 - 1872 . . . In 1823 he married Amelia Full 1893 - 1876, daughter of Lewis Full, born 1765, and Jane Collins Full, born 1768, who came from Potomac Valley to settle Full's Fork in 1818. Jane was daughter of Rupert and Tecumopeas Collins, born 1749. Tecumopeas was sister of Tecumseh 1768 - 1813, and daughter of Shawnee Chief Pukeshenwa, who died at (battle of) Point Pleasant 1774, and wife, former Mary Iaac 1728 - 1823, who was kidnapped because of her red hair, at age 5. Her father, Fredericke Iaac, born in Holland 1680, died 1799 in the Potomac Valley."

The Full's have a family tradition that Jane Collins was the niece of Tecumseh. Also that we were related to the Chief Cornstalk. Jane Collins and Lewis Full had a son, Andrew who married Emma Jane Hartley. Their daughter, Mary Ann Full married Michael Staats Anderson. They are my great great grandparents. The Full and Collins line were in the Seneca Rocks area of WVA and then to Wood, Wirt and Jackson Co WVA.

Does anyone have further information on this line?
