Unless I am mistaken:
Aunt Eileen's name is spelled 'Eileen', not 'Ilene'
Aunt Serena's name is spelled 'Serena', not 'Serene'
When the Geni tools bring up the quick link, it indicates these as half brothers and sisters when, of course, they are the same ones, ie Ilene is Eileen and Serene is Serena. There should have been a conflict table on these.
