Other than the Bee Gees and the Osmonds, were there any famous siblings in the 70's?

Sister Sledge

The Pointer Sisters

Jim Seals (of Seals and Crofts) and England Dan Seals

The Carpenters

The Emotions

Kristy & Jimmy McNichol released an album in 1978 though I don't
know that they are all that famous.

We can't forget The Jackson Five.

from late in the 70s,

-Ann & Nancy Wilson of Heart
-Alex & Eddie Van Halen

Ian Thomas (singer) + Dave Thomas (SCTV)

[quote author=whis

Todd and Marc (RIP) Hunter of Dragon

Tim and Neil Finn of Split Enz (Yes, they were a 70's band)

The Moir Sisters (Margo, Jean & Lesley)

No one mentioned the Jackson 5...

I spose you could count the Beach Boys...sure they were more 60s than 70s, but they were siblings (one was their cousin, and another a friend) and they are my favourite group of all time.

David & Shawn Cassidy (sons of the late Jack Cassidy and Shirley Jones was their step-mother)
The Cowsills
Crystal Gayle and Lorretta Lynn

There were a pair of twin girls named Ginny and Gracie who were well known for speaking only giggerishj to each other.

Dave Loggins (whose biggest hit was "Please Come to Boston" in 1974) is the cousin of Kenny Loggins

The Doobie Brothers  ;)  J/K

This one is 70s/80s ...

Freddie James is the brother of Rozalind Hunt.  Their mother is Geraldine Hunt
All Canadian singers by citizenship, Freddie is best known for the 1979 hit 'Get Up and Boogie' (Top 40 in Canada and the Netherlands) and Rozalind (as a member of the duo Cheri) is best known for the 1982 hit 'Murphy's Law' (Top 40 in the US)


This one is somewhat confusing ...

Bobby, Cecil, Curtis, Harry and Friendly Womack are all famous gospel brothers. 
Here's the confusing part:  Bobby married Barbara Campbell, the widow of Sam Cooke.  Cooke and Campbell's daughter Linda married Cecil (who together had hits as Womack and Womack), which would make Linda the step daughter AND sister-in-law of Bobby

whistledog that last one reminded me of I'm My Own Grandpa.. ;)

A few 70's siblings of the Soul genre:

Gladys Knight & the Pips (one 'Pip' was Gladys' brother)
Cornelius Brothers & Sister Rose
Tavares
Brothers Johnson

Also, did anyone mention Duane (R.I.P.) and Greg Allman?

Lindsey and Sindney Greenbush - Carrie on Little House on The Prarie

Nancy McKeon (Facts of Life) & Phillip McKeon (Alice)

I always remembered those sisters: Audrey was on Dallas and Judy had a recurring role as a hooker on "Night Court" ;D

Don't forget Jimmy and Billy Carter...one was the leader of the free world, the other, a hapless drunk.
Remember Billy beer (at least, I believe that's what it was called. I know he had his own beer at one point)?

Oh, and who can forget the Hansen brothers of Slap Shot fame?

"Just puttin' on the foil, coach...Old-time hockey!!!!"
"They brought their TOYS with them!!!!"

Ronnie Van Zant (Lynyrd Skynyrd) and Donnie Van Zant (38 Special).  Johnny Van Zant took on Skynyrd when Ronnie passed away

In the 70s, there was a singing duo called the Keane Brothers (John and Tom), sons of the legendary label owner/producer Bob Keane.  At age 11 and 12, they became the youngest stars to have their own variety show on TV (which aired on CBS).  Their 1977 single "Sherry" reached US #84 and was a big hit in Canada reaching #25

A book I have says that the Keane Brothers are Canadian, but I can't find other evidence to back that up

Tom and Dick Smothers, Jack and Jerry Brisco, I believe the Osmonds were mentioned, and the Jacksons too.
