I also have the Ras surname in my family. My great grandmother, Katarzyna Ras, came from Korczyna, Poland and immigrated to the United States in 1905. I have information on her immediate family as well as a number of siblings and cousins who settled in New Hampshire.
I tried to contact you through the email address you provided, but it didn't work.
Do you have any more information regarding your Ras line?
