Hi Joe,
Thanks for the help. I'm using the USA Geocoding locator that came built into the Arc software. As far as our data goes, i'm a little stumped, I understand what you are saying, but no matter which way I feed the info into Arc, I get the same results.
For example, if I open ArcMap and do a find on any address in St Louis, it returns a match on St Louis and Saint Louis. Alternatively, if I do a find on any address in Saint Louis, it returns a match on St Louis and Saint Louis. Because it is returning both results, I don't think editing the data will help me, I would assume there is some way within Arc to do this and I just don't know how :).
