- "Peter, I know these last few months have been hard for you. But I’m going to a better place and I will be okay. And I will always be with you. You are the light of my life. My precious son. My little Star-Lord. Love, mom."
- ―Meredith Quill to Star-Lord
Meredith lived in Missouri. She met a a being from outer space and had a son with him, who she named Peter. She gave Peter a walkman with a mix tape of her favourite songs, which Peter adamantly protected from then on. She called him her little "Star-Lord", which an adult Peter adopted as his outlaw name.
Meredith died of terminal cancer in 1988, when Peter was eight years old, but gave him a second mix tape of music before passing. He did not open this second tape until many years later, after defending the planet Xandar as a member of the Guardians of the Galaxy. After taking hold of the Power Stone during the conclusion of the battle to prevent Ronan the Accuser from taking it back, Peter's body begins to rip apart, causing him unbearable pain. He begins hallucinating and sees an image of his dying mother asking him to take his hand. In reality, this is Gamora calling to him to take her hand so that they can share and absorb the stone's power.
- In the comics, Meredith rescued the space prince J-Son and fell in love with him. After his departure, she was killed by two Badoon soldiers, who were enemies of J'son and sent to kill their son Peter.
