Phantom Wiki URL
The wife(s) of the 4th Phantom is a mystery.
We know the mother of the 4th died during childbirth and the 4th was so depressed that he buried himself in studies instead of fulfilling the role of the Phantom.
All we know about the 5th Phantoms mum is that she had dark hair, was English and had family in Nottingham.
