Nelson et al., 2013. http:\/\/dsl.richmond.edu\/historicalatlas\/.<\/p><\/div>\n<div><\/div>\n<div>I was curious about the reference to the lake as &#8220;Lake Illinois&#8221; instead of Lake Michigan. At this point, I don&#8217;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&#8217;t know at this point&#8211;and that&#8217;s not really the purpose of this post.<\/div>\n<div><\/div>\n<div>The reference got me to thinking about what genealogists should do when they see something they think is wrong:<\/div>\n<div>\n<ul>\n<li>Consider the source. Is Raffeix&#8217;s map accurate in other ways? Are there other problems with it? Is Raffeix generally known to have been accurate?<\/li>\n<li>Consider the time. Was the name in use when the map was drawn up.<\/li>\n<li>Consider that the reference could be a mistake or an oversight.<\/li>\n<li>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&#8217;s several generations removed from the original.<\/li>\n<li>Consider that you don&#8217;t know everything. Maybe Lake Michigan was known as Lake Illinois. Even if a person spent their entire life on the lake, it doesn&#8217;t mean that they know everything about the lake&#8211;especially things three centuries before their lifetime.<\/li>\n<\/ul>\n<div>And, consider that place names can change.<\/div>\n<div><\/div>\n<div>All of these things are things to think about even if the reference on the map was an aberration.<\/div>\n<div><\/div>\n<div>And&#8211;it goes to show you that you can always learn something from looking at old maps.<\/div>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>This map, purported to have been created by Pierre Raffex in 1688 appears in a 1932 atlas by Charles O.
