Thomas Brown Hewitt is seen to have a very bulky and big boned body, he is believed to stand at 6’5. Thomas’s skin is light with a tint of pink with blue eyes and black shoulder length matted hair. He has a cleft lip and many scars on his arms due to his work on the farm and in the butcher shop. As an adult, Charlie got Thomas a job as butcher. Thomas generally preferred to stay in his work shop beneath the house, but could monitor activity taking place in the living areas of the home by way of a spy hole in the center of a sliding metal door. Thomas wears the face of most likely someone he skinned and cannibalized, he knows how to sew, and when he finishes his pieces, he eats the parts he didn't use. In late August, 1973, Thomas Hewitt slaughtered several more youths who had the misfortune of coming upon the family's territory. Thomas has a bracelet with charms from all the victims he’s killed, made of teeth and hair. Also, he loves to play with his chainsaw. He is a little slow mentally, but violent, cautious, and when asked to be quiet, he obeys. He only fears and respects his mother, Luda May.

Luda May Hewitt was the only female member of the main Hewitt family. In 1939, as a young woman, she was scavenging for food in a dumpster outside the Lee Bros. Meat Processing Plant. She found a discarded baby in the dumpster with severe birth defects. Adopting it as her own, she brought him home and named Thomas. Luda May raised Thomas as her own child from that point forward. Taking the child as her own, she brought him back to the Hewitt residence and presented him to Charlie Hewitt, who declared that it was the "ugliest damn thing" he had ever seen. Luda May thought he was beautiful however. She is an older woman, with gray hair and blue eyes, and a strong character to keep her two sons, Charlie and Thomas, in check. She loves them both, but she's more inclined towards Thomas because of his mental disability. Cannibal, as the rest of the family. Even though Luda May seemed to do most of the cooking in the Hewitt household

Charlie Hewitt was the head of the family. A stern and vulgar man, he looked after his family with great care. It was Charlie's experiences as a P.O.W. during the Korean War that led him towards the path of cannibalism - a practice he later indoctrinated his family into accepting. In 1969, Charlie Hewitt murdered Sheriff Winston Hoyt who had been attempting to arrest Tommy. He took his uniform and badge and even began using the man's name. As Winston had been the last remnants of law-enforcement in this dying town, Charlie Hewitt became the soul sheriff in the entire county. From that point on, he addressed himself only as Sheriff Hoyt. He is tall, with light blue eyes, and due to his memories as a soldier, his PTSD led him to start cannibalism.

Monty appeared to be the oldest member of the Hewitt family. He may have been the uncle to Charlie Hewitt, though the two seemed to be fairly close in age for such a relation. Charlie referred to him as "Uncle Monty", but this may have just been an honorific. Monty may have been the legal homeowner of the Hewitt manor house, and once referred to it as "his house". In the 1960s, Monty drove a tow truck, and may have been responsible for many of the old broken cars that were found on the Hewitt estate. In 1969, Monty was attacked in his home by a biker named Holden, who shot him in the leg. Rather than use conventional medical procedures to help him, Charlie had Tommy cut off the injured limb. He then had him cut off the other leg to even him up; "For balance", Charlie noted. Both legs, now he's a mad old man on a wheelchair.
