Even though I noted that the marriage record was likely correct, I latched onto a census record (it was very late and I made the mistake of not slowing down to review every detail in my haste to finish my answer). Deb's conclusion that Morris was her LNAB is a better hypothesis. Here's other data that supports that:
1895 Kansas census:
- Kansas State Historical Society; Topeka, Kansas; 1895 Kansas Territory Census; Roll: v115_35; Line: 27. Index.
In Pittsburg, Crawford, KS, there is a 25 y/o Etta Adams, born in Illinois, living with an Al?? Adams, born in Indiana. The enumerator might have gotten his name wrong. Living with them is a 9 y/o James Morris born in Kansas. So you can take this info about another person, James Morris, and try to figure out where he fits by doing a search on him.
* "United States Census, 1900," database with images, FamilySearch(https://familysearch.org/ark:/61903/1:1:MMTD-G1T : accessed 20 September 2018), James Morris in household of Mary A Morris, Pittsburg city Ward 4, Crawford, Kansas, United States; citing enumeration district (ED) 87, sheet 15A, family 330, NARA microfilm publication T623 (Washington, D.C.: National Archives and Records Administration, 1972.); FHL microfilm 1,240,477.
Here in Crawford, KS, we have a James Morris, born in Nov 1883 in Kansas, living with a Mary Morris, age 49, a widow, born in Illinois. His father was born in Missouri, what Etta reported on the census in the later years for her father.
So, the census record I noted is a red herring (it happens) and Deb's answer of Morris is the correct one. I'm switching the best answer star to her.
