William Oldenburg married Susanah Albers, the older sister of my Great-grandmother (Catherine Albers Christen). I have William and Emery's father listed as William Sr., married to Bertha Reese. His father was John, married to Sophia Beckman. I also suspect that John is a brother of Christine Oldenburg Reuter, my 3rd great-grandmother. I would love to compare notes and trade information at some point if you are willing.
