In the list of Jewish Families of Dvinsk in the All Latvia Database at JewishGen there is a note next to the record for Eliah Hurwitz that says he is the son of Josel and the Nephew of Leiser. Apparently Josel was dead. I concluded that Josel was the brother of Leiser and entered him into the family record.
