You look at the record in the

XREF

view to see which cross-reference records should be unmerged. One cross-reference record represents Joe Smith and the other cross-reference record represents John Smith. The child record contains address information that applies to Joe Smith. You create an unmerge task and recommend to the task reviewer that the cross-reference record be unmerged with lineage. Unmerge with lineage associates the appropriate address records with the unmerged record.
