- Consider the source. Is Raffeix's map accurate in other ways? Are there other problems with it? Is Raffeix generally known to have been accurate?
- Consider the time. Was the name in use when the map was drawn up.
- Consider that the reference could be a mistake or an oversight.
- Is the map an accurate rendering of the original? In this case, the image on this blog post is made from a digital image on the website that was made from the 1932 book which was made from the original or a copy of the original. That's several generations removed from the original.
- Consider that you don't know everything. Maybe Lake Michigan was known as Lake Illinois. Even if a person spent their entire life on the lake, it doesn't mean that they know everything about the lake--especially things three centuries before their lifetime.

I was curious about the reference to the lake as "Lake Illinois" instead of Lake Michigan. At this point, I don't know if the description of the lake with this term is an aberration or if there was a time when the lake was know as Lake Illinois. It is also possible that the reference is a simple mistake. I don't know at this point--and that's not really the purpose of this post.
The reference got me to thinking about what genealogists should do when they see something they think is wrong:
And, consider that place names can change.
All of these things are things to think about even if the reference on the map was an aberration.
And--it goes to show you that you can always learn something from looking at old maps.
