I have this situation:
I am not able to delete extra spouse and I am not able to add fake spouse that I would later try to delete.
Merging relationships is almost always the best course of action and usually in this situation clicking "Add Spouse" then adding just "peter," and deceased fills in that extra spouse slot and lets you merge Peter Rybar and peter. I can't see why you can't do that without doing this for you. But do try that again
The other option in a situation like you have where a person has this format of parents is to delete the relationship to the parent who does not have a spouse. Do this by clicking on the little paper and pencil icon next to the child's name and working through the popup windows:
This will remove the relationship of Anna and just her mother and leave the relationship to Anna and both her parents.
Glad you got this to work. There is an absolute minimum of information we always need to add to create a new person. These are:
When those three things are entered, the Save button becomes active.
Thank you. The secret I did not know was that I am able to add fake person after I tick deceased. Strange.
