In my canvassing of cemeteries in Pawnee County I found no stone for a Henry Adams. However, in the Pawnee Times Democrat of 3 Mar 1910 there is a death notice for Henry A. Adams who died circa 26 Feb 1910 and was buried "at Pawnee". He is identified as a Pawnee Indian, so most likely is buried in the North Indian Cemetery just north of Highland Cemetery. But it is possible that he was buried in Highland Cemetery.
My plans right now are to finish my research into cemtery records, etc. by the end of next summer and then publish the information in book form. However, that depends on prepublication sales, and my own financial status at the time. So it may end up going on-line depending on my situation when the time comes.
