Sura Rebecca Sztezrnis was my great grand mother. she married Moshé Aron Kronental in Varsovie. She died around 1900. All daughter and sons came in Paris between 1912 and 1925. My great grand father also. I look for her brothers and sisters. I find one in Paris Abraham Sternis (1974- 1942). One of her sister married a Berliner, and another one a Glajchman. I would like to know their name, and how many siblings they were.
Thanks for help
