The De Leon family were, according to a hand-written note from my father, "relatives of the Abraham family. First cousins from Rustchuk."
I'm assuming this means the De Leon brothers and sisters were cousins of Moritz Abraham, which means that either Mamo Abraham or Lea Jacob had a sister who married a De Leon in Rustchuk; hence there should be a connection to either the Abraham or the Jacob family branch.
There were three brothers: Isaac, Abraham and Henri, and two sisters: Visa and Sarica.
Although the De Leon were related to the Abraham family, they stayed in contact with Ronya after the death of Moritz (as evidenced by photos sent to her in the mid to late 40's). Ronya also seemed to be in contact with Visa until her death.

Isaac immigrated to Palestine. An agronomist, he studied in Montpellier in 1922 in l'Ecole Nationale d'Agriculture with the help of Moritz Abraham's financial support. Specialist in citrus for the Government of Palestine.
