I'm looking for information on the Halpern side of my family. My great-grandfather was Barnie/Bernard/Baruch Halpern. Originally from somewhere in Russia. He came to the US with his parents, Sarah and Morris Halpern sometime in the late 1800s or early 1900s. He may have traveled with his brother Leon and sister Rose as well. He was here prior to 1913 and living in Philadelphia. He was introduced to my great-grandmother, Sophie Swidler, by his Aunt Sora Swidler (née Halpern). Both families knew each other in Russia--the Swidlers come from a town named Chemerowitz. They had three children: Sidney, Claire and Miriam.
