Never assume that a person with what you think is an usual name might not have a “name twin” somewhere. There were two men named Lubbe Albers living in Illinois at the same point in time, in different parts of the state. They may or may not have been cousins, but the marriage index and census records indicate that they were different men living in different places at the same time–and not the same person.

Don’t just grab the first census hit and assume you have the right person.
