Marriage certificates of that time period in Kansas do not name the parents, basically the bride, groom, ages, places lived, official performing the marriage, and witnesses?? A better bet will be to look for a marriage announcement in the Atchison newspaper.
Send a letter (with SASE) to the cemetery requesting birth and death dates and burial locations. They will respond but it may take a month or so. With the death dates you can look in the Atchison newspapers for obituaries. Ask for all your surnames.
