Thanks. Since posting I have found quite a bit about the Gunnings in Enid, Garfield Co., OK. Nothing on Laura.
A great site to find info in Garfield Co. is http://bjsbytes.com/garfieldhttp://bjsbytes.com/garfield Be sure to scroll beyond what seems the end. Click on the dots for Marriages, Enid Cemetery, Vetrans, etc. Census records also have them listed.
