I have a list of names and addresses that I want to turn into mailing
labels. (bob/smith/100main/town/...)There are many instances of people
living at the same address (pam & bob & jonny/smith, sue/jones each at 100
Main).

Is there a way to extract a list of all combined multiples so there is ONE
Smith instance at 100 Main?
It would need to list if there was a Jones there too for an additional
label.

???
Thanks
