Looking for any information on my grandfather who lived in the Hancock Michigan area. His name was Alexander Koski. He had five sibilings, Yalmer, John, Hannah, Edward, and Olga. He actually was born in Sing-Sing (spell?) in the Keewenaw area. Then lived in a house in Hancock near Santori Corner. Moved to Detroit after WWll. Do not have any information of his family who may still live in the Hancock area. Any information, would be greatly appreciated.
