Family & marriage
Click here for the main page of the Dutton family.
Monica's ancestors had lived on the northwestern plains for centuries before finally ending up on the Broken Rock Indian Reservation. She herself grew up on a ranch  and had a brother named Robert. Her grandfather Felix Long is one of the Indian elders on the Reservation. 
She started her own family by marrying Kayce Dutton, the son of big cattle rancher John Dutton and his by then deceased wife Evelyn. Monica and Kayce had a son they named Tate and they lived on the Broken Rock Reservation. 
Her brother Robert and Kayce's brother Lee ended up facing each other in a feud between the Yellowstone Dutton Ranch and the Reservation. Robert shot Lee and was about to finish the job when Kayce interfered. He saw that his brother got shot by Robert, his brother-in-law, and had to kill him to protect himself and his brother. He soon found out he had not only killed his brother-in-law but was too late to save his own brother as his gunshot wound turned out to be fatal. 
Monica was hit when trying to stop a fight between two school boys. She passed out while recovering at home.  In the hospital it turned out she had suffered an subdural hematoma and she had to have brain surgery.  In time of recovery her marriage took a turn for the worse  but she and Kayce overcame their problems and eventually started to live on his home ranch. 
When Monica and Kayce were on bad terms and she had to go in physical therapy, Monica took her relationship with her therapist Martin to the next level. It did not last, however, as Monica and Kayce gave their marriage another try.
