Hello, I am researching the Dickson- Sparks Line also. Our Isaac Dickson born 1802 or 1803 died in Illinois 1890 was married to Katherine Sparks. They married 1823 in Kentucky and moved to Indiana. He seems to appear from out of nowhere. He states that he was born in Pennsylvania and Virginia. NO record of him. None that I can seem to find.... Hope you have had luck.
