I don't know where your Hillhouse'e were but there was a David Sloan Hillhouse in Kemper Co, MS. He had a son Jesse Sloan. They were also in Ky. i think Livingston Co in 1810. I found some information on them just this past week. I have a friend researching Alexander. In his patent for land there is a reference to David Hillhouse being his brother-in-law. We haven't found a connect yet.
