My grandmother married an Emery Oldenburg. They had three children Merle Oldenburg, Elaine Oldenburg and Lester Oldenburg who died when he was 5. My grandmother was Anna Oldenburg. My aunt, Carrie Oldenburg married her brother Harley Oldenburg. They had one child Karsten Oldenburg. They lived in Dane County most of their lives. I know there were cousins, one was a lawyer I believe. Any significance?
