Re: George A. JONES b. 1874, OH/Addie R. TEEL m. ca 1897
The Sandst3 family tree shows that George Alesco Jones b. Dec. 11, 1873 married Adda Leel 10 Nov 1896 in Osceola, Polk, NE. Most larger libraries provide free access to Ancestry.com.
You can contact Polk County Clerk, www.polkcounty.ne.gov/content/marriage.htm to order a copy of their marriage license.
I checked Ancestry and FamilySearch.org but didn't find the marriage info. Successful Searching!
