Grady Franklin Stiles, Jr., was born in Pittsburgh on July 18, 1937, the sixth in a long line of lobster-men (preceded by William Stiles, 1805-1888; Jacob Stiles, 1843-1932; Elisha Stiles, 1880-1935; and finally Grady Stiles, Sr., 1912-1988). Grady could not walk and used a wheelchair in public, but could crawl around on his incredibly powerful arms and could perform nearly any task using his "claws". He was married twice to Mary Teresa Herzog and once to Barbara Browning and had four children, two of whom, a boy and a girl, also had lobster-hands. When his eldest daughter Donna was engaged to marry a boy of whom Grady disapproved, Grady shot and killed the boy.

However, Grady escaped a prison sentence on the grounds that no prison was equipped to handle his disability. He was given fifteen years probation, and soon after the trial re-married Mary Teresa and continued to physically abuse his family. In 1992 Mary Teresa mentioned to Grady's son-in-law, a circus employee, that "something" needed to be done about Grady's abusive behavior. On November 29, 1992, he was shot to death while watching television in the family's trailer home. The killer was a neighbor, hired by Grady's son-in-law.

The surviving Stiles family members still call Gibsonton home. Cathy is married to carnival worker Tyrill Berry and is the mother of Misty, born in the early 1990s, who also has the lobster-claw condition (ectrodactyly). Grady III has a daughter, Sara, who does not have ectrodactyly. Cathy, Grady III and Misty still perform occasionally. Cathy has appeared in the films Sisters (1973), Tim Burton's Big Fish (2003) and Firecracker (2004) as well as in an episode of the series Carnivale.
