Delaney was born in
Lansing, Michigan, and raised in
Cincinnati, Ohio. His family moved to Jacksonville when he was sixteen. His father, Jim, was a mid-level executive with General Motors, retiring from GM in 1982, and retiring again in the mid-1990’s after being later-rehired by GM. His mother, Mary Anne (Langius) was a school teacher, retiring after John and his brothers were born. Her father, Adrian Nelson (Gus) Langius was the long time State of Michigan architect (FAIA) and state building director. Jim and Mary Anne went to high school together, but did not start dating until sophomores at college. Mary Anne transferred from the University of Michigan to Jim's Michigan State University, where both graduated. John has two younger brothers, James Langius (Gus,) a retired long time budget analyst and auditor for the state of Florida, and Joe, a crime analyst for the Jacksonville Sheriff's Office. He graduated from
Terry Parker High School in 1974. He was captain of the debate team, was a regional champion and was offered a number of debate scholarships to colleges/universities, including to the University of Florida. He declined the scholarships to focus on his studies. At the
University of Florida, he joined
Delta Upsilon fraternity, graduated in 3 years and received a
B.A. in 1977. He did some post-baccalaureate work before starting law school in 1978. In 1981, he received a
J.D. from the
University of Florida Levin College of Law, passing the bar the same year. He later received an honorary doctorate from Edward Waters College, now Edward Waters University. Delaney and his wife Gena met in 1979 and married in 1980. She graduated from UF, then went on after their first two children were born to obtain a Nursing degree. She worked at St Vincent's Hospital. They reside in
Neptune Beach, a town on a barrier island off the coast of the mainland of Jacksonville. Their house is the home Gena grew up in. They have four children: Bill (Katie), Adrian (Will) Milford, Meg (Drake) Skinner and Jimmy (Payton.) John and Gena have five grandchildren. They also helped raise a niece (Rebecca Keeney (Maldonado) (Husband Jorge) and a nephew Nathan Keeney (Paola) when Gena's oldest sister died in a car crash in 1987. Rebecca and Nathan have three children total. Bill is a published author and co-owner of the blog, The Jaxon and of the local magazine, Edible. Gena retired from nursing when John was elected Mayor to care for their children, and to also help care for her mother. (Both of Gena's parents lived with the Delaney's until their deaths in 1985 and 1997, respectively.) Delaney graduated law school and passed the Florida Bar exam in 1981 and was hired by then
State Attorney Ed Austin, becoming Austin's chief assistant state attorney in 1985. He was the youngest Chief Assistant of the 20 judicial circuits in the state at the time, and still was when he left the courthouse in 1991. Austin became a second father figure and a role model to Delaney and to many of the thousands who worked for Austin. Austin was one of the most influential figures in Jacksonville history. When Austin was elected
mayor of Jacksonville in 1991, Delaney became the city's
general counsel for two years, and served as Austin's chief of staff for two years. Delaney ran for mayor himself in 1995 when Austin declined to seek a second term. Austin endorsed Delaney. ==Mayor of Jacksonville==
