I am looking for any information on my great grandfather on my mother's side. He was born in Russia and immigrated to New York in 1888. He married Daisy Belle McMullen in 1896. They had three children, Walter Vivian Clark, Mary Clark and Charles M. Daisy was born in Auburn in 1868? or abouts. Any help would be appreciated. He may have come to the USA with another last name and changed it when he got his naturalization. Not sure.
