Uncle Cecil is Greg's adoptive uncle that is only 3 or 4 years old according to Greg. He was adopted by Greg's Great Aunt Marcie. Although he is only a toddler, he is considered an adult as he sits in the dining room with adults, even though Rodrick has to sit with kids.


  • In real life, it is theoretically possible to have an aunt or an uncle that is younger than you, since they are the sibling of your parent.
