The JewishGen Family Finder (JGFF) is a database of ancestral towns and surnames currently being researched by Jewish genealogists worldwide.

By using the JGFF, you can learn about others who are seeking ancestors of the same surname or town of origin.

ORIGINAL RECORDS AND LOCATING THEM

Births, Marriages and Deaths :  Most of the existing records are available on microfilm through Family History Centres run by the Church of Latter Day Saints.  This is a short guide of records specific to Leypuny available on microfilm

1808-1825 Jewish births, marriages and deaths were recorded by the Parish Church in Leypuny .  These records have been microfilmed.   Extractions of the  Jewish records found in these registers  will shortly be available  at http://www.jewishgen.org/JRI-PL/patronym/status.htm  click on town name Leypuny. Similiarly, the Patronymic records for Kopciowo and Wiesiejie  have also been extracted and can be found at the same place.  I have digital copies of the patronymic records.

Most of these records have been  indexed for  the JRI database.  You  may also find some of the vital records for people in this town in later Lazdijai films  which have been indexed.  As some of the families came from Merkine, those records will prove to be of interest as well.  They are available on film and are in Russian and Hebrew.  Translations are underway and will be added to the LitvakSIG  database.                                                                                                                                                                                                  

LitvakSIG is the primary internet source connecting researchers of Lithuanian-Jewish genealogy worldwide. Its purpose is to discover, present, and preserve information about our ancestors' lives in Lithuania, and to better understand the lives they led, before the destruction of 95% of Lithuanian Jews in the Shoah.  http://www.jewishgen.org/Litvak

The Suwalk-Lomza Interest Group for Jewish Genealogists    focuses on the former Russian-Polish gubernias (provinces) of Suwalki and Lomza  as constituted in 1866-1914.  They  publish a quarterly Journal called Landsmen, which offers original research and data extractions, chiefly from material pertaining to the 19th century. The journal is not available online.  A description of the contents as well as details of membership appears at http://www.jewishgen.org/SuwalkLomza/
