My G-grandfather Wilhelm Hupke came to America in 1873 from Gernamy. He settled in Illinois after arriving in the USA. His son and my grandfather Carl Hupke moved to Oseloa Co. Iowa. Looking for relatives of his brother and sisters. His brothers name is Wilhelm Hupke and sisters names are Wilelmina; Bertha; and Auguste. Bertha's married some one with the surname Mack, she lived Chicago, IL. Auguste married some one with the surname Miller, they lived in Windom, MN. SSDI record list her last known address as Kasoda, LeSuer Co., MN. My grandfather had cousins by the surname Hopkey could be Wilelmina (Mina) married name??
