Yeah, I've no doubt that some of my ancestors in the census, the data was filled out by a neighbor going "And the oldest boy Jimmy, he's the same age as our Veronica, but the baby, everyone calls him [name that has no bearing on reality], he was born the year of the big snow storm, now was that 07? or 09? " the 1860 census, they got everyone's name and age right EXCEPT their last name, so instead of Marsh, they're all listed as Myers.
What I really want to see happen is someone transcribe the census data with the locations, particularly for this reason--I have a couple of family members where the system can't find them, which probably means they're spelled wrong. But most of them lived around their family members in previous years, so if I could look at the location data longitudinally, it would probably be a lot easier to find them.
