Aunt Veronica is the middle sister of Susan Heffley and her other sisters and is Greg, Rodrick and Manny's aunt. She hasn't appeared at a family event in person in a long time and often appears in video conferences.
After really thinking about it, Greg realizes that he probably hasn't seen his Aunt Veronica in person since he was at least three or four (toddler age).
Greg thinks that family events stress her out and that's why she doesn't visit. Later she can be seen on a tablet held by a man as she was guiding him where to search for the diamond ring.
Aunt Veronica's last name is unknown.
She is similar to Lawrence on Greg’ paternal side who is always busy and makes appearances through webcam.
