pandarain on Family Tree Circles

I am looking for ancestors of my grandfather, Joseph Junker, who was born in Dusseldorf, Germany, on October 31, 1888. He was in his teens when his family came to the United States. He married my grandmother, Esma Calhoun, of Carroll County, Mississipp, and they had two children, my father, Loranz Junker, and my aunt, Jeanette Junker, who married John Avon Patterson. My grandfather and grandmother divorced at some point in time. My mother and father died when I was young. I do know my grandfather was in World War I and is buried in the Veterans Cemetary in Gulfport, MS. I found this out on the internet. This is all I know. Any information would be very much appreciated.
