I'm afraid I can't help with Isaac. I have an Anderton family, that of John Washington Anderton and Mary Heath in the Bedford-Moore-Coffe county Tennessee area about one generation prior to the dates of the Isaac you're looking for. There is a very good library in Winchester, TN that might be a source for you if you haven't looked there. Best of luck to you. There were other Andertons in Bedford Co. TN.
Children of John Washington Anderton and Mary T. Heath are:
Sallie Anderton b. 1862 G.J. Anderton b. 1863 Willie Anderton b. 1869 Robert Edgar Anderton b. 30 Dec 1858 d. 24 Jul 1955 m. Martha Elizabeth Evans 25 Ma 1895 Moore Co. TN (see later) Nellie Anderton b. 1871 Harold Byas Anderton b. 13 Dec 1871 d. 29 Feb 1960 m. Arrie Ray (see later)) Luther Anderton b. 1873 Mary J. Anderton “Jennie” b. 1874 m. William Riley Ray (see previous) Emmett Anderton b. 1875 Mary Anderton b. 1878 Ollie Anderton b. 1882
