My search has led me to believe that Dunn/Cohen families are from Zasliai, Lithuania. Israel (James) Dunn married about 1880 in Lithuania to Minda Cohen the daughter of Tzvi. 5 children were born between 1881-1889: Charles(Israel) 1881, David 1883, Elizabeth(Elak) 1885, Ida(Naie) 1886, and Frances(Feigi) 1888. Israel immigrated 1889 and Minda immigrated 1893. Minda died 1913 in Manhattan and Israel Dunn died 1931 in Bronx. Israel Dunn/Donn father is Isaak Donn and his mother is Bessie(Elizabeth) Bernstein. Minda Cohen had 5 siblings that immigrated to New York: Sarah Cohen married Lifshitz, Max Cohen married Dora Vinitsky, Rebecca Cohen married Dorman, Ida Cohen married Friedland, and Hannah/Anna married Kronenberg.
