Officially approved since 2014.
Forgot to write that in 2014 I’ve got Ph.D. in history for the demographic study Jewish population in Piotrkow Trybunalski, 1808–1870. The study has been developed in to a sub-project for International Institute for Jewish Genealogy Family and Kinship in the Jewish City of Piotrków Trybunalski in the 19th Century.
The database build for the purposes of these projects is searchable through MyHeritage search engine, it covers births (1808 – 1875), marriages (1808–1888), and deaths (1808–1870). For additional information on the individuals from these databases, please write us.
