She gets to keep the will when Rose passes away, stated in The Truth Will Out. Kirsten was shocked when she found out her father made very little money, as Rose always told her that he was successful and hardworking. She basically dissed her mother, but then they made up at the end of the episode. She has one daughter, Charley Adams.
In the episode Home Again, Rose: Part 2, Rose had to get triple bypass surgery and the girls, being very concerned for Rose, called Kirsten. By the time she got to the hospital, she saw the girls singing a song. She took this the wrong way, thinking the girls did not care for her mother. Until the end of the episode, Kirsten would not let the girls see Rose after her surgery because they were not Rose's family. When Kirsten allowed Blanche, Dorothy and Sophia in to see Rose, she said "My mother needs to be with her family now."
