I am looking for any kind of information on William C. Mitchell and his wife Caroline "Callie" (Wolfe) Mitchell. These would be my great grandma & great grandpa. William apparently died somewhere around 1929, but this is all that I have. William's name is on the Kay County Court House on a plaque. I have no dates of births, deaths, marriage or where they maybe burried. If anyone could help it would be greatly appreciated.
