Dr. McElhinney was the family dentist when I was a kid growing up in Duncan. His office was on 9th Street, a half block north of Main on the east side of the street, directly behind the Rexall Drug Store and across the street from the Western Union office. I remember him as a tall man (but maybe at my age all men were tall) and a very friendly, kind person. I have no idea if the Duncan Banner keeps an OBIT file, although most of their issues are on file on microfilm at the Duncan Public Library. You might try checking with Grantham Funeral Home, which is still in business in Duncan and was there during the '50's; the only other funeral home, as far as I can remember, was the Boydston Funeral Home, but there is no longer a funeral home in Duncan by that name. Good luck in your search. Duane Monkres Edmond, OK
