Joseph Wallace

If any of you are connected to the Wallace Family you will find this interesting.  Joseph  Wallace lived in Ohio County during the 1830's and in 1830 was granted two Patents related to water-wheels. On the second image below you will find "Current water wheel, for mills" and on the third image you will find "Motion to mills communicated by a water wheel."  I think Joseph's family owned a mill in Ohio County that was powered by a water-wheel.  There is a Joseph Wallace in the 1820 census living in Ohio County. I found a Gazetteer from 1840 that says Ohio County had two flouring mills and seven grist mills
