The pilot missing with English Premier League footballer Emiliano Sala is the ex-husband of a woman who lives in New Zealand.
The small plane flown by David Ibbotson with Argentine striker Sala on board went missing on a flight from France to Wales on Monday night.
The search was abandoned on Wednesday, with search and rescue teams saying they held no hope of finding survivors and the operation had become a recovery mission.
The Daily Mail said 60-year-old Ibbotson's ex-wife is Georgina Gymer.
Gymer's sister Linda Goodwin told the Mail that neither of them knew Ibbotson was on the missing flight.
