Searching for relatives of my Great-great grandfather, Manaleh Shaul Rosner, born circa 1825 in Rostocki, Ukraine. Born to him was son Yehuda Leib Rosner in Viznitz (?) Ukraine. Born to him was my Grandfather Isidore Rosner who immigrated to U.S. in early 1900s.Anybody out there know the parents/brothers/sisters of Manaleh Shaul or Yehuda Leib? With Shalom, Debbie.
