An aunt died, after bearing 3 children. The uncle remarried and they had a child, who I erroneously attributed to the first wife. How do I correct that?
You need to detach or remove the child from the first wife. You can then add that person as a child to the second wife. Please give me the PID in FamilySearch and I can take a look at it and better help you.
Hope this helps,
First things first ... advice/hint
DO NOT "Delete"/"Remove" the Child from the Aunt (who died) and Uncle, to start with.
That said ...
Take note of; or, copy, the PID, for the Child.
IF, you have not already; THEN, add the NEXT Spouse/Wife to you Uncle.
IF, or, whence, done; THEN, "ADD" the Child to your Uncle and his next spouse.
NOW you can "Delete"/"Remove" the Child from the Aunt (who died) and Uncle.
Better to be safe, rather than sorry ... Add first, then Delete/Remove last.
That way you do not loose track of someone, it is so easy to do ...
Been there, done that ...
You can use the "Remove" or "Replace" option in "Parent-Child" Relationships; but, unless you are confident and know what you are doing, the steps I suggest are the safest.
Just my thoughts.
