Angela Petrillo is the widow of Sophia's son, Phil. She was described by Sophia in the episode "A Little Romance" as a welder and a hard-drinking woman whose father had a fortune hidden away. However, in "Ebbtide's Revenge," Angela was portrayed as a cosmetics saleswoman whose father could only pay $47 for the dowry to marry Sophia's son, Phil. Sophia even called Angela "Big Sally" because she thought she was trashy.
Angela loved Phil unconditionally, despite the fact that he was a cross-dresser, and he even wore a wedding dress at their wedding. They had ten children together, six of them boys and four of them girls. One of them, Harvey Petrillo, was supposed to graduate from Animal Grooming School, but flunked out.
In 1990, Phil died of a heart attack at the age of 55. While Angela stayed at Blanche's house, she learned with the help of Rose's experiences at a grief counseling center that Sophia wasn't just upset about the $47 dowry, which Angela paid back to her, but the fact that she never stopped Phil's cross-dressing. Angela answered that he's been doing that all his life. Afterward, Sophia said that she always wondered what she said and did to make Phil the way he was, and Angela told her that he was a good man. Sophia broke down crying, and Angela hugged her.
