Leo Lilly, better known as Grandpa Leo, is Pepper Ann, Moose and Ned's grandfather, Lydia and Janie's father and Lillian's husband.

He first appears in "Thanksgiving Dad" when he and Lillian show up seven and a half hours early to Thanksgiving dinner because they were bored.

He was a Private in WWII and met Lillian when she performed at a sendoff at Lupkin Park. The two bonded instantly and were married not long after, 50 years prior to the events of "Cold Feet" (roughly 1947).
