Dad in this case just happens to be Bruce Crouch, the former Bartle Bogle Hegarty executive creative director and a founding partner of Soul.
So where did the 6ft 5-inch 21-year-old - who scored 19 goals for Pompey after joining the club from Queens Park Rangers last summer - inherit his ball-playing skills?
Apparently not from Crouch senior, a goalkeeper whose delusions of grandeur never got beyond turning out for London Transport in the Chiswick League and a guest appearance for Heart of Midlothian Supporters Club at Wormwood Scrubs (don't ask).
"Was I any good? Probably not as good as I thought I was,
"But we knew Peter could play from the age of six."
And how will Crouch fils cope with a life of booze, birds and the sybaritic Midlands nightlife? "He's very well behaved and level-headed," his dad insists. "Not like me. I'm from the Gazza school of enjoyment."
However, the Crouch family loyalties will be tested to breaking point when Villa face Chelsea - where Bruce is a season ticket holder - in the final game of the season. Split allegiances? Not a bit. "I've told Peter that if he scores he'll be coming back to a one-parent family."
