If you have linked to people together, either as spouses, or as parents, by mistake, you can unlink them. This will remove them either from being a spouse in the currently selected couple, or from the family in which they appear as child.
Ensure the person you wish to unlink is the active person, i.e. they are the person who appears in the edit panel. Then select the option required from the “Edit” menu. For example, to unlink from the current spouse, choose “Spouses” > “Unlink ...”.
Note: there are two options: “Unlink from spouse and children” will unlink the currently selected person from this family with a spouse/and or children; “Unlink spouse from me” will unlink the spouse from this couple, leaving the current person still linked to any children.
You will be prompted with a dialog to confirm you are sure, and then the unlink will be applied.
If you have made a mistake, you can use “Undo” from the “Edit” menu to undo the unlink, so long as you haven’t made any other changes in between.
Important: If you unlink the person from their spouse, they will also be unlinked from any children they have with that spouse. You may need to unlink the spouse with the spouse as the active person if you wish to keep the children with the first party, and only unlink the second party.
