Mary DEMSKY Schaffer/Shaeffer was my great grandmother. Her husband's first name was Isadore. They supposedly came to this country in 1890. There were 6 children: Jacob/Jack, Alexander,Ida,Selma,Becckah and my grandfather A(a)ron. I have more information posted in mssg archives of JewishGen. I also just came in contact with a cousin. He and I will be exchanging more info shortly and updates will probably appear in JewishGen.
