First off, thanks for the info. I have those links and I have some trouble using them. I do not like the layout. I have to give props to Ancestry, love the site...good layout. Two, jewishgen shows that there is a town Koszowka that was also in the Russian Empire(pre1900) and now in Ukraine. I will have to try that line next. My grandfather always identified himself as Polish and not Russian.
I have attached ship records just so that you can see where I got the info.
