Hi -
I'm also seeking info on this couple; I'm trying to complete a Descendant survey for a James Callin, and Nona's mother, Bessie Viola, is his 2x-great-granddaughter. I'm hoping to confirm whether Nona had any children.
[Update: I probably posted prematurely.
Making some changes to the following.]
Based on the information on the WWI Draft card, I looked for John Dent in Akron, and found him listed in the U.S. City Directories database in 1912, 1914, and 1915. In each record, he is listed with no middle initial, and works for the Goodyear Co. In 1912 his address is 24 Irvin, and in the 1914 & 1915 records, "rms rear 53 S Case Ave".
I couldn't find any U.S. Census record for John and/or Nona in 1920 - at least not in Ohio. Up to this point, I'm reasonably sure this is the John Dent we're all interested in, and that Nona is probably living with him at the addresses listed, at least until 1918 (when the WWI Draft card was filled out).
After 1920, there are more U.S. City Directories records in Akron - these all list a John M Dent, with a wife (I assumed) named "Oleta". This IS a different John Dent from the one we are concerned with. I determined this from looking for Dudley and Mark Dent (bolded in the transcribed records below) in the Census; in 1910, the whole family is in Center, Monroe county, Ohio - about 130 miles south of Akron.
Since these are just city directories, there isn't a lot of information about how the people listed might or might not be related to our John Dent, but this should give you an overview of the other Dent folks in Akron, Summit county, Ohio over the years:

I also found an Ohio Birth Index record:
Name: Bessie M Dent
Birth Date: 24 Aug 1911
State File Number: 1911061076
Additional Information: McFann
In that database, the "Additional Information" field usually either has the father's given name or the mother's maiden name - so it seems highly likely that this Bessie is the daughter of Nona and John Dent... most likely the stillborn daughter the original poster mentioned above.
If anyone is interested in examining these records I've transcribed here, I ought to be able to share them from Ancestry. I'll share whatever they let me share!
Cheers,
Tad Callin
