Like his father, Christopher joined the US Air Force. He married and had two sons - Scott and Alex. Christopher with family often visited his parents on vacation.
One day, when Christopher with family were returning from vacation, their plane was destroyed and entire family was believed to be dead. In truth, however, Christopher was kidnaped and spent subsequent years as space pirate Corsair, while Scott and Alex suffered traumatic amnesia and were separated from each other after the incident.
Only many years later had Philip and Deborah learned that their son and grandsons were still alive. Christopher had reunited with his now adult sons and reintroduced them to their grandparents. Unfortunately, they came at the busiest season, so Philip and Deborah could not met them personally and sent their new employee - Madelyne Pryor - instead.
Philip and Deborah attended Scott's wedding with Madelyne Pryor. When Scott left the X-Men he, Madelyne and their newborn son Nathan settled down in Anchorage with Philip and Deborah.
After Scott left to join X-Factor, Madelyne and Nathan stayed in Anchorage. She continued to work in Philip's company until he sold it to Nathaniel Essex.
Several months later Scott visited his grandparents to tell them that happened with Madelyne and their son.
In recent years Philip started to lose his eyesight. Realizing that soon he would be no longer able to fly a plane, he decides to fly for one last time. Unfortunately, he couldn't control the plane and it crashes down. Deborah called Scott to inform him that Philip is disappeared. Scott and Jean both travel to Alaska to help with the search.
Philip is found and hospitalized next morning. He completely lost his eyesight, but Deborah is happy that he managed to survive at all.
