She has been mentioned several times throughout the show.
Willa mentions that Ward, her husband, would abuse her. When this happened she would take the girls to Swan Reservoir.
- She has been assumed by characters and fans alike that she was still alive, as she walked out on her children when they were young, never to return. In I Hope You Dance, we find out that she is indeed alive.
- In the episode Purgatory, her name is listed as Wendy Rossie on the family tree Waverly has made. However, in I Hope You Dance, Wynonna mentions her mother's name is Michelle. Emily Andras has explained on a twitter post, that the name Wendy Rossie was written by the Art Department, so as to fill a void on the wall. It should not be thought of as canon.
- Her Granddaughter, Alice Michelle is named after her, along with Alice's other Grandmother (Doc's mother), Alice Holliday.
- The character of Michelle was named after Creator, Showrunner and Executive Producer Emily Andras' best friends, both named Michelle. One of them, Michelle Lovretta is the Creator, Executive Producer, and Showrunner of the TV show, Killjoys, as well as the TV show Lost Girl. Emily has written for both shows.
