Find everyone linked to a place
There are two ways of searching for people associated with a place:
1. You can use the Find > Places search to find any person who has a link to a place. It will search ALL events to find people asscoiated with a place. But the place name links are very fussy. "Cairns, QLD, Australia" will not include "Edge Hill, Cairns, QLD, Australia". Even when you select "places containing" Cairns you are presented with a list of all such places and you have to work through them individually to find who is associated with each place.
To find people married in a place you need to use Find > Search Families.
SO.. either method has its pros and cons.
