This response may be a little late but I have recently been advised that the Kusa Cemetery is located ca. 1/2 mile east of the old Kusa townsite on Trugeon Rd. that comes east out of Henryetta (about four miles)to a place once called 'Four Conners'.There is nothing there now. At this intersection (the only one there)turn south for about one mile. The old cemetery will be off in a field on the right side of the road. I am told that it is grown-over and not easy to find. Hope this can help you find you relatives burial site.
