Most times you’ll be adding a sibling to someone whose parents are already shown, thus the siblings share the same parents – that’s the easiest way of adding siblings.
Let’s try adding a sibling to Francesco Tornabouni (Selvaggia’s husband) Note that Francesco’s parents are not known.
When you add a sibling to someone with unknown parents XY Family Tree creates 2 unknown people, married together, so that the siblings may share the same parents. (All siblings must share at least one parent.)
We now have
Two unknown people and a marriage between them
These can be edited later if you have more information.
Of course, if the father and/or mother were already shown, XY Family Tree would have used these and not have created new unknowns.
