In 1961, Arleta filed for divorce from Merle Sr., as his mental instability was worsening. Allin and his brother were from that time raised by their mother and stepfather, and settled in East St. Johnsbury, Vermont, in 1966. Arleta changed her younger son's legal name to Kevin Michael Allin on March 2, 1962, during his first year of schooling. Arleta had allowed his birth name to stand until this point and finally changed it to give her son a chance of a mockery-free childhood.
