I am hoping someone can assist me. My maternal great grandmother was Nechama Birenbaum. According to her Blitzstein Bank and YIVO records, she was born in approximately 1858. She took the S.S. Haverford from Hamburg (via Liverpool) on November 2, 1907 with my great aunts, Reise (Rose) and Dabe (Dora) and arrived in Philadelphia on December 7, 1907. One of her other daughters, Shprintze (Sophie), was my grandmother, who had arrived in Philadelphia the year before. Under the “Passenger Address” space Nechama listed “Abram Goldfarb Wisoko Litowsk - Brest Lit Gub Grodno." The purchaser of her ticket was my great grandfather and her husband, Michel Schmukler (aka Shmookler), who had emigrated from his “last place of residence” of “Brisk" via the S.S. Werkendam, arriving from Rotterdam to Philadelphia on February 13, 1900. Here is my question. I recently discovered several Birenbaum relatives on Ancestry.com. We are certain we are related because in my family photo album I discovered photos of Birenbaum relatives (first names unidentified) that I have shared with my newly discovered cousins and which they confirm as their father and great uncle; also my Great Aunt Rose’s grandchildren took a DNA test which confirmed that we are related to the Birenbaum cousins with whom we have recently been in contact. The mystery is that we do not know how Nechama (also known as Anna in the U.S.) and our newly discovered Birenbaum cousins are related. Their Grandfather and Uncle, Morris (Moshko), was born in the town of Kleshelyah, in the “Nemirovskaya Community” in the “Bilsky Borough” in the “Grodensky” Region on October 16, 1906. This comes from his birth certificate. Morris' parents were Pinkos (Philip) Yankelavich Birenbaum and Perlya Birenbaum. Pinkos arrived in the U.S. in 1913, at around the age of 40; this means he would have been born in approximately 1873. I am guessing that Pinkos (Philip) and Nechama were siblings but it is only a guess. Does anyone have any guidance that could tell me how Nechama and Pinkos Birenbaum may have been related? I have searched JewishGen and Ancestry.com but have not found any connections. I have no information about Nechama’s parents or siblings.
