When Macy was born both her parents weren't expecting her. Her mother apparently got pregnant when her father had come home one night, drunk and barely able to stand on his feet. Her mothers' pregnancy was a so called 'I didn't know I was pregnant'-case. Her mother had been drinking and doing drugs during her pregnancy, but Macy came to life healthy. Because of her father's addiction and her mothers lack of interest in her she didn't really have the best start in life.
Because her parents weren't capable of taking care of her she had to learn how to take care of herself from a very young age. She had done some things to take care of herself and one day she met a lady that asked her why she wasn't wearing a coat. It was december and freezing outside, but Macy had no money to even buy one. The lady soon realised that Macy wasn't been taking care of and she decided to look into her family life. She soon found out that Macy had been living under horrible circumstances and that she wasn't been taken care of.
The lady decided to put Macy in the foster system as Macy was still a minor. She soon found Dylan and Alyson and Macy went to stay with them for a while. When she was two years in the care of the McKenzies she gets injured due to some stupid mistake she made. When Dylan and Alyson ask her if she would be willing to become their adoptive daughter she agrees. There is nothing she would rather want.
