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.

I’ve got one that’s even a bit more twisted… My g-g-g-grandfather, his wife, and 3 children. All 5 names appear twice in the 1860 census in the same township in Lawrence County, Ohio, but several pages apart and with slightly different ages (+/- one year). Our family, like many others, was really big on namesaking, but this is nuts.
Was the census enumerator being paid by the numbers and my family was duplicated to pad his pay? Were they cousins who married women with the same name and both had two girls and one boy at approximately the same time?
In determining which record was the true record for my family, I look to the neighbors. One of the records is surrounded by surnames I recognize in my family history while the other is surrounded by names I’ve never seen before.
