One of the first names that came to mind was Mark Thatcher, son of former British Prime Minister Margaret Thatcher. He got lost in the Sahara desert while competing in the Paris-Dakar rally. IIRC he also received millions for being involved in an arms deal with Iraq brokered by his mum.
I searched for information about the Sahara desert incident and came across this
MT is mentioned at the end of the article but it’s interesting to read about the kids of the other people as well.
My vote: The Novelist Tabitha King
Not to say he is devoid of all talent, but would we know who Jim Belushi was if it weren’t for John?
Speaking of John/Julian Lennon…Paul McCartney has a brother who cut a couple of records, Mike McGear. I think he had an awkward time because he really did try to distance himself from Paul, but it couldn’t be kept secret that he was Paul’s brother, and he ended up being perceived as a flake who was riding on Paul’s success- so his career went nowhere.
(He looks nothing like Paul, and would be ideal as an impersonator of a “Bleeding Kansas” John Brown in the pic - yes I majored in history.)
And Baboon, since Enrique Iglesias was mentioned, may I add Cristian Castro? His mom sure has both of her talents still intact though, and she must be over 50.
OK…it was me who put her name under “talent”…and yes, I hedged when putting her name down. In retrospect though, you might be right…plus, like many other celebrity kids with borderline talent, she threw up her free lunch by bottoming out and selling her body for drugs. Recently seeing the light, she is now trying to re-start her “career”.
Hence, like any good French judge at the Olympics, I recant my vote and now revoke Natalie Cole’s name from my “talent” list above.
Thank you for keeping me honest, AHunter3.
What about the current CEO of Disney? I’d say that is the most blatant example of this I’ve ever seen.
Jason Connery (Sean’s son). I’ve seen a few of his films, he no impression on me, regardless of the role.
Neil Connery (Sean’s brother, but I think he only made the one film)
Don Swayze.
Lana Wood (Natalie’s sister, but she sure was hot!)
Casey Wagner (Robert’s daughter) a host on the TV Guide Channel and was in Dill Scallion playing a country music VJ, basically another host.
Every son of Kirk Douglas but Michael.
Jimmy Kimmel cousin (forgot his name). Oh wait, Jimmy Kimmel isn’t talented either.
BTW, astorian, Frank Sinatra Jr. is famous for getting kidnapped in the 1960s. But no talent needed there either.
Sorry, that Katie Wagner, not Casey Wagner.
Ooh, ooh! Operation Kid Brother AKA Operation Double 007, an MST3K classic!!
“Prepare to meet Kali’s brother. Near Hell!!”
In 1998 he took court action to prevent his kidnappers from profiting from a movie about the kidnapping.
A few years ago I read an article about Frank jr that led me to believe that he was hindered in his career by being Frank’s son. People would see him and automatically compare him to dad even though jr was primarily a lounge jazz singer.
He is a trained composer/arranger and was for many years his father’s musical director. Other than hiring him for this gig, his father did nothing to aid his musical career. I imagine since he’s still performing he just likes the job.
On the opposite side of the OP, Al Jolson paid his brother a lifetime salary to stay out of showbusiness, because he wasn’t up to Al’s lofty standards.
Check out this cast:

And I forgot:
Cusacks can act. Both are great.
I also forgot:
Stallone’s son: Can’t act.
Stallone’s brother Frank: Can’t sing.
Imagine the shame of being even less talented than Liza! 
HYJACK
LifeOnWry, where the hell have you been!?!?!?
Did we frighten you in October?
But collectively: can dance a little.
isnt his dad famous too? I am thinking its Loco Valdez for some reason.
I saw previews for a movie a while ago. It had Jack black in it. I think it was Orange County. I swear, they mentioned it twicce:
…And Tom Hank’s son as…
wow. what a way to start the downward slide.

Would those who want to slag off the ‘talentless’ Nicolas Cage please muster at least enough ‘talent’ themselves to spell his name correctly?
[/slight hijack]
Ahem, and now back to your regular scheduled thread.
I think the outstanding example has to be the idiot dysfunctional offspring of our own dear Aged Parasite, The Queen. With the possble exception of Anne, not a single one of them has demonstrated any merit, talent, ability, skill or competence whatsoever, and they’re all so impressively thick as a brick one wonders how they ever manage to walk upright.
I like the Culkins. Macaulay, ironically enough, is the only one who really has no talent - but yet he was the famous one.
But Keiran is amazing, and Rory looks like he’ll be good in the new Shyamalan movie.
All of these posts, and nobody mentions “the daughter of Vanessa Redgrave…the wife of Liam Neisen…no wonder she won a Tony without being able to act.” (Thanks to Forbidden Broadway).
I use to know a girl whose name was Liza.
She was so good the critics all despised her.
She use to go out hopping in gay barland.
Matter of fact, she sang a lot like Judy Garland.
Ramón Valdéz, maybe his nickname was Loco, was indeed famous and Cristián’s father. He died about 20-30 years ago, and was the grumpy poor neighbor in the TV show El chavo del ocho , broadcasted throughout Latin America…it still is in some places.
Oh, and I agree with you, Cristián Castro is talentless.
Also, Enrique Iglesias has 2 other brothers (from the same father), who have try to break into the music world, again using their father’s name.
No, Ramon was not el Loco Valdez.
(he was more of a show MC/comic). He is still alive.

no way, his dad was Ramon? you sure?
Wow I hated Chavo del Ocho.
Mom used to make us watch it with my cousins.
Tori Spelling? Her dad: producer who cast her in the tv series, “Beverly Hills, 90210.”
