Masterchef The profesionals - Which one is the child of a famous person?

[befuzzled]

Is bugging me, thanks

I think one chef was the son of a famous head chef, but he got knocked out several rounds ago (red haired chap)
Any help?

I keep thinking I have seen Ash somewhere before, no idea why, his face is very familiar. Maybe he just looks like someone , it's odd I'm usually pretty good with face recognition.
