Thanks to all for the answers! Maybe I have a cheapo setup? The hovering method works only for the "unconnected people" list. There is no trace of a column Status/ID.
And then there is also the matter of the ancestry tree diagrams (which has been the subject of several questions over the years). Many links in the style "Adam, son of Eva, married Eva, daughter of Adam". Or, for the Laidlaws, "William son of William son of William..."
In both situations, the lack of clarity arises mainly from the irritating habit of families giving their children only one first name, and that from a very limited list. For the female members, the number of Kraus Annas is also astonishing.
Since the name should ideally - for our purposes - provide an unambiguous identification, I suggest that a workaround - so long as the trees do not show the ID - is to add the ID as a "second name". In my case, this would simply mean instead of 40 x Johann Kraus ambiguously cluttering up the picture, they would be entered as Johann 2010 Kraus, Johann 2035 Kraus etc.
Maybe it's not pretty, but it would considerably reduce the ambiguity, and thus some of the errors that take hours to correct.
Any thoughts?
