I went to Poland about 12 yrs ago. I had a Polish interpreter and he went into the archives and found a lot of info on Kons Kohns, etc. There is also a town there called Konin. You are absolutely right on about the names - they changed the spelling a lot and then when the immigrants came over here they changed them again. I was trying to find any long lost relatives as all my father's family perished in the camps - but I didn't turn up anything - but I always seem to have to ask when I see a name with similar spelling. What town in Poland were your family from??
