Leon was a butcher. Immigrated to Argentina with Bernardo after the death of Elena, to Colonia Dora in the province of Entre Rios, the Chaco region, and married there. Called himself a "Jewish cowboy". Brought over by Baron Hirsch. See Gabriel Braunstein's discussion of the Jewish immigration to < href="http://www.reocities.com/Paris/Musee/7075/argentina1.html"> Entre Rios, including a table of the major Jewish colonies in Argentina. Baron Hirsch's colonizaton started up in 1905 by that table.
Family tradition suggests origins in the Ukraine or Rumania. A very plausible origin would be the agricultural colonies of the southern Ukraine, set up specifically for Jewish colonization after 1846.
