Melissa, Thanks for responding to my posting. My Grandfather and his brother(name unknown) left Russia (the Ukraine) at the same time, about 1905. The Russo -Japanese war was in 1904-1905. My Grandfather Samuel Kneler and his wife, Molly, came to the United States (Philadelphia, Pennsylvania) and his brother went to Argentina (Buenos Aires). My Grandfather's name was changed to Keller by the Immigration Authorities. My Father, Nathen Keller (Kneler) was born in Russia and came over with my Grandfather and grandmother. Can you give me any other details? Do you and your family live in Argentina or the US?
