Hi Bill, I don't have much on Addison, I have more info on his brother Preston S. Brown my hubby's direct line. I know Addison married Lucinda Isbell in Todd County Kentucky and they moved to Newton County MO in about 1840. They had George Isbell Brown. Addison had about 1000 acres of land in Newton Co. George Isbell had 3 sons, Dewitt, Addison, and William who became a doctor. Bill my email address is HILADY3480 for more info. Judy
