I am also looking for the Szternszos family from Kielce. My grandmother's mother's family was from there - we have pictures even. We now live in Toronto, Canada. They were related to the Ladowsky family too. I don't know much about them other than their last name and city though, and I know that it's an obscure spelling. Please get in touch with me if you know more. Herbert Stern, who posted above, had a very interesting lead. Please get in touch with me if you see this.
