I'll kick it off with 'Roseanne' -- Jackie and Roseanne were close sisters. It was believable because they fought and it wasn't all sunshine all the time.

'Wings' -- Brian and Joe Hackett were great as brothers with the troubled past relationship.

Buffy,Jody and Cissy from Family Affair and Willis and Arnold from Diff'rent Strokes. Because of deaths of their parents they needed each other more.

Eight Is Enough - Mary, Nancy, Nicholas, David, Tommy, Susan, Elizabeth and Joanie. They had their ups and downs, but were definately there for each other as well.

The girls from Full House
Jackie& Roseanne
Larry Daryl and Daryl
Sonia and Buzz-Mama's Family

Non- Sitcom:
The Barkley Brothers- Big Valley
The Walton kids
The Ingalls girls- LittleHouse
The Cartwrights-Bonanza
Pam and Cliff- Dallas
Bobby and Gary- Dallas

Also:

- Willis, Arnold and Kimberly from Diff'rent Strokes
- The Tanner sisters from Full House
- The Keaton children
- Ashley Banks and Will Smith from the Fresh Prince of Bel Air

They were cousins.

How about Alex and Mallory on "Family Ties"? Sure they argued a lot, but their relationship was real. I have an older brother, and I can totally relate to those two.

Friends - Monica & Ross

Yes!! They argued, but loved one another when it counted most. I am the older brother of a younger sister (2 yrs. like Alex and Mallory) and I know where they came from.

Frasier and Niles Crane

Yay, somebody agrees with me! LOL My brother reminds me of Alex, too, in a lot of ways (I haven't decided yet whether that's a good thing or a bad thing! ;))

The Barone Boys are the best siblings ever BY FAR.

Not from a sitcom, but the first pair of siblings I thought of was Willie and Buddy Lawrence in Family. They had a great relationship and it seemed fairly realistic (at least to me). I miss that show.

The Tanner girls (Full House) didn't seem to fight alot. And they loved eachother and told eachother they did.

I'm sure they're more.......

What was so great about Monica and Ross was that they hated each other as kids and grew to care so much about each other..as adults...plus she fell in love and married with his best friend from college and he in turn was in love with her best friend...

another brother and sister pair....Joey and Gina Tribbiani......they stick up for each other.

"I'm gay for David Cassidy." Joey

"If you hurt my sister in any way, I will hunt you down and kick your ass." Friends
