Eddie Daugherty (1892-19??)
Ray, Edna, and Stella were known since childhood. 'Eddie Daugherty' is the shadowy 4th I learned of in '06.
Possible common ancestor between him or Stella and Ray or Edna, there's some 23andMe info to support that.
An image, the summary reasoning posted here once I've tracked him down.
The 1920 census shows an "Ed W Daugherty"
Actual name is 'William Edward Daugherty' (1879-1945), wife 'Sterling Stella Boyer' (1879-1961)
Daugherty is a very common name in the region so it's just a start since it's the right area, Morgan Co., IL.
I had confabulated him being a light skinned black that decided to pass but being white
and married but not to Stella Burns better fits available current evidence.
By 1920 he would have had 3 or 4 children by Stella (Burns)
and my father, (paternity uncertain) could still have been the 5th.
In any case the combination of archival and genetic info will ultimately reveal the truth.
I once met the Burns in the East St. Louis area (1965) and they were quite dark, darker than my father or uncle, more like Jimmy and Erlene in pic.
