Without actually deleting everyone and starting from scratch, how do I move the children from the second wife to the first wife, please??

Go to each child's page and click the edit box (by the child's name)

Go to the bottom of the new page and you will see boxes identifying the parents.

Change the mother's name to the correct name

Click SAVE

You cannot, in one stroke, change the status for all children. They must be done separately

As it turns out, I, sort of, did this by deleting the "First" wife and changing the name of the "second" wife to that of the "first" wife. All sorted!

Now I've got to find out if the deleted wife was real or not!!

Thanks for helping.
