Luke Farmer appears to have had more than one wife. I can not cite sources, as the names I have came from message boards. You will need to authenticate these, but I have Jerusha Barnes as wife # 1, his 2nd wife unknown, Elizabeth Fleming is #3, and Mary Seymore #4. His children George and Elizabeth were from wife#2, Theo and Wade from #3, John Grace, Thomas Jefferson, Eliza, Sarah and Nancy from #4. Good-luck proving them, but I hope it helps you get started.
