The Lurie Legacy: The House of Davidic Royal Descent by Neil Rosenstein. Compiles the sources for Rashi (and hence Davidic) descent of major rabbinic families through the Luria (Lurie) family. The Lurie family is a very ancient family, tracing its roots back through Rashi and Hillel to King David. The book is a comprehensive study of the Lurie/Luria family that includes 45 pages of family trees showing the relationship of the Lurie family to such other families as Epstein, Eskeles, Heilprin, Isserles, Katzenellenbogen, Margolit, Meisel, Mendelssohn, Pereira, Weidenfeld and Wulff. The text portion of the book is filled with the history of the Lurie family, critical analysis of previous works about the family and legends by family members penned in the 19th century. More than 60 documents of the Lurie family illustrate the book, the earliest dating back to the 16th century.

Charlap-Yahya Organization: Eastern Europe, Spain, Portugal, Israel. A Jewish genealogical organization and research initiative comprised of well over 17,000 entries, 7,000 of which are living and current members; this extended family spans multiple continents and hundreds of years. The name of the organization originates with the first Ser, the son of Abraham Charlap, born circa 1740. At the time, Charlap was not a surname but an honorary title; an acronym consisting of four Hebrew letters, standing for “Chief Sage of the Exile in Poland.” The Charlaps are a distinguished rabbinic dynasty, whose yichus is well established. They stem from the Ibn Yahya (Don Yahya) rabbis of Spain and Portugal and before that go back to the Exilarchs in Babylonia and Persia.
