Go the Change Log of the surviving person. Find the merge that was in error. Click on the deleted person.
If there have been no edits on the survivor the top portion of the page will have an Undo Merge llink. Clicking there will undo the merge.
If there have been any edits on the survivor, it will say Restore. Clicking there will restore the deleted person to the exact state prior to merge. It will not make any changes to the survivor and will you will have to manually take off any information on the survivor that was put there during the merge.
Thank you Collett. I am still in trouble as one of the children has been assigned to two parents, or more correctly a mother has been been assigned to two husbands.
Thanks for your help Collett. I have managed to correct my errors. Regards. Joe
