Just above the Marriage Date is that [unknown spouse] entry.
In this case, there was a gentleman with no children, NO Spouse entered. The key is that there is that marriage date.
The above is in People Workspace, TreeView
This is different from an "unknown" spouse if you have a Spouse with a Child.
Clicking on the Person menu, select Attach/Detach option and DETACH
Put a check mark in the Unknown Spouse "name". You need to watch IF there are Children.
In the case of one spouse and a child, without a Marriage Date, that "unknown spouse" may appear in the Person View, but nothing to Detach.
For my screen capture example, putting a Check Mark RESOLVED that Unknown Spouse, but the Tree View did NOT Change.
I have not found an easy way to find these "unknown spouse" entries, but they usually come from a Merge.
I found this one, by running a Marriage Report, Sorted by Wife, then looked for a Marriage Date at the Bottom of the list.
There is a Caution Here. That is the Marriage DATE will be removed. So, BACK UP your file before you do this OR, If you don't like the results, immediately do a Edit, UnDo
