Hi,
In theory (and as claimed in the documentation for place record editing), if you edit the place name in one record and that same place is used by other records, you will be warned about the pending change and have option to alter the way that change is recorded. For example, when I changed "Bennington, Bennington, VT, USA" used by three individuals in my file, I got this alert:
The name change to 'Bennington X, Bennington, VT, USA'
is a new place name for this file. Choose one option:
• 'Create' a new place record for 'Bennington X, Bennington, VT, USA'
• 'Change' name for place 'Bennington, Bennington, VT, USA' to
'Bennington X, Bennington, VT, USA' (which will change it in the
other events that cite this place too).
• 'Try Again' to choose a different or an existing place
Here "Create" will create new place record and only the current person will be linked to it. In contrast, "Change" will change the name for this place and therefore will change it for everyone linked to it. "Try Again" cancels the save process and lets you edit the place name if you want. If, however, that place is only used by one person (or one family), the place name will changed without asking you to make a choice. This change is only affected a single record and therefore should always be intended and safe.
Did you get that warning? If yes and you clicked "Change" it will change that place for everyone using it. If not, it might be a bug and I will double check. I could not tell exactly what you changed to be sure.
Perhaps you changed the name to a different place, but one that is already in the file. This change proceeds without an alert, however, is only changing the place in the person and is not changing anything in any place record or any other person of family. For example:
1. Say your file has place records for "Orangeburg County" and for "Orangeburg District"
2. Now go to a person with place name of "Orangeburg District". If you click the "PLAC button" you described (it is meant to be a compass), it will open the place record for "Orangeburg District" and you can use the "Referenced By" command to see all the people linked to that place.
3. Now back in the individual record. If you decide to change "Orangeburg District" to "Orangeburg County" what you have done is tell GEDitCOM II to link this one person to a different place record. It will do so, but the only change that is made is to that person. No place record or any other person of family is affected. But, if you click that "PLAC button" it will now open "Orangeburg County" instead of "Orangeburg District" and "Referenced By" on that place will show all new people - these will be different people. If you looked at your places and opened the "Orangeburg District" record, you will see it is unchanged and still links to all the previous people (minus the one you changed) and nothing else has changed.
Perhaps that is all that happened? In other words, the "PLAC button" link is linking to the place name currently in the place field and therefore it will link to a different place if that name is changed to another place already in the file (Hint: another way to open the place record on any place field is to control (or right) click on the field and choose "Open Place Record" from the pop-up menu.)
Two more options
1. I will look at the code and see if it might be possible to not be alerted of possible-unwanted changes.
2. Perhaps a clearer way to edit place names is in the place records themselves rather then in the PLAC fields of individuals and families. By this path, it is very clear that changing a place name is changing that for all people linked to the record.
