Eddie Daugherty (1892-19??)

Ray, Edna, and Stella are my known grandparents, plus a shadowy figure known to me as 'Eddie Daugherty'.
He should be fairly easy to locate but have not yet found any leads.
An image here is expected eventually.
    Could literally be a missing link with a common ancestor between him or Stella and Ray or Edna, there's some 23andMe info to support that.    

The 1920 shows an "Ed W Daugherty" head of household and wife Stella in Illinois but they are both listed as white
with two children with unfamiliar names and their ages are a bit higher than expected 40 and 32 instead of late 20s/early 30s.
However Morgan county is about the right location. It suddenly occurs to me that Eddie being married to someone else while fathering children with Stella, a black woman would explain a lot.
