Mary-Ann Quinn's Mother

 is an unseen character in Grand Theft Auto V.

Biography
The only place Mary-Ann's mother is mentioned is on Mary-Ann's Lifeinvader page. Her name is nowhere to be found, as her Lifeinvader profile name is simply "Mother".

On Mary-Ann's page, she leaves a comment mentioning a man her and Mary-Ann's father met at their bridge club, and that he would be a nice companion for her. Her wording in the post also implies that she is aware of Mary-Ann's clear anger issues.
