The best info that I have seen says they moved to Americus Township, Lyon Co., Kansas in 1865. According to find-a-grave, Isaac's father was Joseph Brown, Find A Grave Memorial# 42293266. Isaac's mother was Laura Steele, daughter of the Rev. James Steele. As far as I know, she and her mother both died in Kentucky, where James had a church for a short time after leaving South Carolina and getting to Randolph Co. Ill. Actually , I think Joseph Brown went to Randolph Co. and James Steele went to a different county in Ill. I have found no evidence that anyone has ever found Laura's or her mother's graves or the the location of James Steele's short live church in Kentucky.
