The Dallas star was Linda Gray. Linda Evans starred with John Forsyth and Joan Collins in Dynasty, a contemporary of Dallas.
Oops, got my Lindas confused and yes, I can imagine Barbara Stanwyck as the matriarch since she usually played formidable women.
And Taylor Sheridan, the writer of Yellowstone, plays the part of Travis in the series. He knows how to handle a horse, which is amazing to watch.
