Mother McCready

"Mother McCready" is the name given to the mother of Mavis, Mae (Daisy Mae), and Robert (Mac) McCready. Her actual name is unknown and she is an unseen character on the show.

In "One Train May Hide Another," Uncle Mac discusses how his mother would verbally abuse him and make him do most of the housework because he was "Momma's man of the house". However, this was just an excuse for her to go to bars and drink and sit out on the front porch, drink, and talk about how much she hated Mac's father.

It is indicated sometime in Season 2 that while Mae was being raped and molested, she did nothing to stop this. Also, either her or Henry McCready would lock Mavis in a shed for days and sometimes weeks.

Death
In "One Train May Hide Another," she was coming home from a night of drinking and was walking on some train tracks, when she was hit by an oncoming train. She died instantly.
