The Kansas State Historical Society has newspaper microfilms available for Inter Library Loan to your local library or LDS Family History Center.
It appears that they have microfilms of 5 Atchison newspapers covering the date of the wedding. You will have to get the microfilms and see if any articles describe the wedding or the bride/groom.
Search at this link for the microfilm numbers and then have your librarian ILL them.

Use Atchison for the county and 1871 for the start and end dates.
I also suggest you take a look at the KSHS ILL policies from the link on the search page.
Good Luck
