Hello Kayelinda,
Welcome to RootsChat.
As you know I had been helping Mark a while ago with his Hart ancestors from Siemiatycze.
The chances of progressing do not look good. According to the Routes to Roots Foundation
http://www.rootschat.com/links/0bds/, very few documents from the community have survived. The following are held at the Polish State Archives in Bialystok:
• Kahal / Community records (1861)
• Holocaust Records (1942-43)
• Polish Alijah Passports to Palestine (1929-1939)
Have the experts at JRI-Poland discovered any further records?
Rgds,
Justin
