I'm across the river from you, and my understanding is that a lot of the incorrect street names on online maps come from data sources with older names. E911 apparently caused a certain amount of upheaval with road names. Some of the online mapping services seem to have compromised by just listing all possible names for a road, whereas OnX seems to be working off of a different (older?) data set than nearly everyone.
