Member of the Galician Skala Research Group (SRG). Racheli's contribution to SRG includes
  • Maintenance of the SRG contact list
  • Recruitment of new SRG members (see SRG new member form)
  • Help with projects concerning the Righteous among the Nations
Development of the Skala House Number Database - The house numbers in which family members in Skala lived are being mapped, using vital records, tax payer and voters lists. This unique database has provided genealogists with the names of family members who lived in the same house but did not have the same surname. It has enabled the creation of novel links between family trees.
For example: Revealing the link between the branches of Shimon Wiesenthal and his sisters Golde and Beile (all three were living in house number 27, according to their marriage records) led to the establishment of links between the Wiesenthal-Schwartz-Weidenfeld branches of this family.
