Can you give some advice in narrowing it to a manageable number of emails?
the first thing to do is find out if any of these are looking for you
or if other people are tied into the family.
Do a name search at ancestry.com or genealogy.com
posting the names on different sites might allow them to find you.
find a message board at a Tarnow website and leave a message there. some city websites have genealogy links and forums.
try to find a phone directory for the area. online directories are of no use.
edit: are your initials N.S. it's just that i've seen some similar posts.
