Miriam Weiner's site & Chernigov
If you haven't had the chance to take a look at Miriam Weiner's updated website, www.rtrfoundation.org, I recommend that you do so. There are 3 areas of her site that I recommend that you look at for Nezhin and other Chernigov records. Specifically, check out the links:
As mentioned on JewishGen, by Marilyn Golden, Miriam "created a surname database (searchable via standard search and OCR search) which enables the researcher to access Holocaust name lists, vital records, census lists, school records, property lists, various telephone & business directories, most of which does not appear elsewhere online. Written permission was obtained from archivists, authors and institutions for me to create data files & publish this information.
The data entry is ongoing.
A town name search can produce: 1: archive data for that town, 2: images of the town, and 3: link to street map of the town.
A surname search can produce 1: document results with that surname, 2: link to a street map, and 3: links to town images. All in a single search"!
