Eminem's father is Marshall Mathers II. He abandoned his family and moved to California when Eminem was 6 months old. Eminem has expressed his anger towards his father in several songs, often very graphically.
In a 2001 Interview with the BBC, Eminem's father Marshall II seeked forgiveness and said that he would love to be reunited with his family.
I desperately want to meet my son and tell him that I love him. I want him to know that I'm here for him if he lets me back into his life. I'm not interested in his money. I just want to talk to him. I want him to know that I'm here for him if he lets me back into my life.
Eminem's mother Debbie Briggs-Mathers has claimed in interviews that he was constantly drunk, used drugs and was violent towards her. She even claims that he was out hanging out with his friends when Eminem was born. His irresponsible behaviour finally culminating in him walking out on his family.
Marshall II denies these claims and provides a different version of the story. He claims that Debbie took Eminem and walked out on him. He claims to have returned to an empty apartment and was devastated to find his wife and son gone. He drove around for weeks but couldn't find them. Finally he gave up and remarried in 1975.
Eminem's grandmother Kresin told The Source magazine -
Marshall used to colour pretty little pictures and give them to me. He’d say, ‘Grandmom, can you give these to my Daddy?’
She tried to get them to his dad through a relative that kept in touch with him. When Eminem was in his teens, he even tried to write some letters to his dad, but they always came back marked “Return to Sender”.
In another interview with The Source Eminem recalled being at his aunt's house when his father avoided and ignored him in other ways -
I was always over there, and he would call there. I would be on the floor colouring. I remember! I would be there just listening. He would call there and talk to them, and never ask to talk to me.
In another interview on TV, Kresin said -
I think a lot of anger came because he was raised by his mother – no father image or figure was there.
