It's not so much that I can't seperate them, as it is the need to keep 
them together for business reasons.

There is at least a "primary" (tax Owner) address in every case, along 
with possible secondary addresses in the cases of Duplexes and Apt. 
Buildings, etc.  All Addresses need to be viewable, even if I seperate 
out the Primary, there would still be instances of secondary stacked 
points.  I'm still researching this at this point to gather options.

The data is all in a Oracle DB
