There is a book called "History of a Proud Heritage: Ponca City, Oklahoma, A Pictorial History 1893-1960." I understand that page 11 has something about my great grandfather: W.A.T. Robertson, MD. He was one of the first doctors in Ponca City. I assume that this book is in many of the public library genealogy rooms of Northeast Oklahoma. I'd appreciate a scan or copy of the page. Thanks!
