I was doing research on Tracy Mulder's husband, Gerrit John Buyert, who was the 5th of 6 children, and whose parents emigrated from the Netherlands to America the same year Gerrit was born. I searched on Ancestry.com, and found that the Buyert family had already submitted Gerrit's pedigree chart. So I started copying down the information. Garrit's parents, Aart Buyert and Lubertha Buijert, were born and married in Kampen, Overijssel, Netherlands, and emigrated to Iowa. So I continued on Aart's side: his father was Klass Buyert, and his mother Henrietta von Schellen. Klaas's father was Gerrit Buyert, and his mother was M. G. Ruitenberg. That was all the information on Aart's side. So I started on Lubertha's side. I noticed the similarities of surnames, and thought: pretty cool that she didn't have to change her name. It must be a common name in the Netherlands. I wrote down Lubertha's father and mother: Hendrik Buijert and C. Longevoort. I then wrote down Hendrik's father and mother: Gerrit Buijert and M.G. Ruitenberg. Wait. Didn't I write that down before? Yep. Sure did. So, unless there's a typo in the pedigree chart, Gerrit John Buyert's paternal grandfather and maternal grandfather were brothers. That means that Gerrit John Buyert's mother and father were cousins. Crazy! I told my roommate, and she said that things like that were more common back then. Maybe so. Still. Maybe it's a typo after all. Unfortunately, because all the records are held in Holland, it would be difficult to find out if it was a typo or if it is accurate.
