Brock married Patricia Weller (Nellie V. Weller, born 1930, died 2020) in 1949, with whom he had a son and daughter. The marriage proved to be an unhappy one and was dissolved in 1964. The traumatic experience of marital conflict and divorce permeated his poetry at the time, for instance in the bitter and powerful An Arrangement for Seeing Children. In 1964, Brock married Elizabeth Skilton to whom he remained married for 33 years until his death.
