Unfortunately, many early GEDCOM imports arrived without including the connections between the people in the GEDCOM. This seems to be one of them.
The contributions history for the member who created that profile is at this link. The people in the huge GEDCOM they imported in April 2013 seem to be largely in the United States (Indiana, Illinois, Missouri, Iowa, Kansas, and Kentucky, for example), and I noticed some immigrants from Germany and Sweden, as well as people who lived and died in Staffordshire (England). Based on that, I think that North Dakota is a reasonable location.
