I'm not sure what timeframe you are looking at. However, I have a Elijah Willis Koonce among my ancestors. He was born in 1843 in Tennessee and died in 1920. He married Sarah C. Bolerjack on July 26, 1865. She was born in 1840 and died in 1894 (she wasn't a Native American.) They had one son Andrew Jackson Koonce born November 8, 1870. Hope this helps.
