When adding data into FTM 2012, I inadvertently re-entered my maternal GGrandpa. I merged the two records, and later when looking at the pedigree chart realized that GGrandpa wasn't listed.
I went to the person menu>Attach/Detach Person>Attach Child...> and received the error message: "These people cannot be attached because one of them is already a direct relationship of the other".
Now I know there is (somewhere) stored this link, but I can't seem to find it. How do I restore the correct relationship between son and father?
