   | Name: Feinstein, N. |  
   | Born: |  
   | Died: |  |  |  
   | Notes: |  
   | Di Felice in Chess Results 1921-1930 has 'Feinstein, A.' at Brussels 1930, but it is not clear to me whether this is the Estonian player active 1904-1909, and in Chess Results 1931-1935, Di Felice has only 'Feinstein' (with no initial) at Antwerp 1931. |  |  |  |
