The International Institute for Jewish Genealogy and Paul Jacobi Center have recently initiated a large project with the object of publishing the late Paul Jacobi's 114 typewritten genealogical compilations (monographs) on European rabbinical and other prominent Jewish families (see The task of preparing these trees for publication in MS Word is being crowd-sourced outside the Geni environment. To participate, IIJG has invited volunteers to contact Ami Elyasaf at

A large number of the trees covered by the Jacobi materials have been previously added to Geni - and corrected - by family members and genealogists with first-hand knowledge or access to original sources. We invite the IIJG to utilize our crowd-sourced and curated family trees as a resource in building its online presence.

Furthermore, by design the Geni trees have a large number of living descendants of virtually every rabbinic family included in the Jacob monographs. The IIJG is welcome to contact the Geni Curators working on this Project should they wish to identify living descendants who could play a role in a DNA study to further confirm the accuracy of these old rabbinic family trees.
