Leslie Pyenson MD FACP

Jewish farm school “Eydelman,” founde 1900 in Minsk.
I believe my Grandfather, David Pyenson (Paenson in cyrillic or Paiensohn in yiddish) graduated from this school in Minsk in1904 prior to his arrival in the U.S. in 1905. Where might I find more information, class lists, etc?
