I am indeed a HILLHOUSE!! I live on a farm in Tennessee that has been in my Hillhouse family since the 1830s. I'm just down the creek from where John H. Hillhouse, husband of Bethia SHARP and son of Mary Dickey/James Hillhouse, is buried. My nearest neighbor is Randy Hillhouse, 1st cousin; my dad lives nearby. Within less than two miles are my cousins Norman and Donnie Hillhouse, Donnie's children David, Jeff, Nicky, and Carrielyn plus David and Nicholas' children. Another of my really close neighbors is my dad's older brother, Ozro; his daughter spends weekends here. And Randy's parents, brother, and sisters live in the county. I'm very fortunate to have an excellent Hillhouse support group handy!
I just checked my data base. I don't have John Monroe Hillhouse. I do have a James Monroe Hillhouse, 1851-1917, son of Jennett Isabella LYLE and Jesse S. Hillhouse and husband of Eliza Elmira CARSON. Could this be who you are searching for?
