Thanks for the information and the site. I have managed to track down most of the information on him that is available at the moment available on ancestry.com. I also found his death certificate and his parents names on it are Abraham and Mottle. I have found a trip back to Kiev that he and my great grandmother took in 1932. The name on that trip is Rowinsky. So I think that is the most common spelling of their name when it is not spelled Rowin. But I have also found it spelled as Rowinski and Rovinsky. I also have reason to believe that Mottle died in 1932 or 1933 because my grandaunt's middle name is Mottle.
I appreciate all the help and information I can get since most of his family never left Kiev.
