Looking for the title of old Harlequin

[lauren holly]

Old Harlequin Romance. Can't remember title or author's name.

Young woman's sister dies and heroine takes her child to raise. Gives up everything. When story begins, she is working at a concession stand at a rodeo. Meets man who offers to take her to his ranch and take care for both her and the baby if she will marry him. She does. Story is typical romance from there.

Can anyone help me with this???

Sounds like a Janet Daley storyline from back in the seventies. That's a place to start anyway.
