Richard Kuklinski and his wife, Barbara, had three children during their marriage: Merrick, Christin and Dwayne. Merrick and Christin are the couple's daughters, and Dwayne is their son. He also has two sons whose names have not been publicized from a previous relationship.
Merrick, the eldest child, was born in 1964. Her birth came two years into the couple's marriage. After her birth, the Kuklinski family moved to Sunset Street in Dumont, New Jersey, where their daughter Christin and their son Dwayne were born. They continued to live in the same house until Richard was finally arrested in December of 1986. According to Barbara Kuklinski, Richard was married to the mother of his first two children when they met and began dating.
