The Mara Family Legacy

The Mara family is an Irish-American family primarily known for owning the New York Giants of the National Football League (NFL) since the franchise was formed in 1925. Timothy J. Family patriarch Tim Mara was born in 1887 in New York City to John and Elizabeth (née Harris) Mara. While working as a newsboy, Mara also earned money as a courier for bookmakers. Mara was married to Elizabeth "Lisett" Barclay for over 50 years. Jack Mara was born in 1908. In 1934, he married Helen Phelan, daughter of New York State Athletic Commission chairman John J. Phelan. They had two children: Maura and Timothy J. Helen Mara later married Joseph C. Nugent.

Family Dynamics and Involvement

Maura Mara was described as "probably the most rabid in the family" by her cousin John Mara. She married Richard J. Concannon, a senior partner at Kelley Drye & Warren, and had three children. Wellington Mara was born in 1916. He started as the team's waterboy and after graduating from Fordham University joined the Giants as team treasurer and head of football operations. After his brother's death in 1965, he assumed the role of president. Mara was heavily involved in league affairs. He was instrumental in creating revenue sharing that saw all teams split profits from television contracts and helped engineer the merger of the NFL and American Football League. He remained team president until his death on October 25, 2005.

Internal Disputes and Resolution

Timothy J. Mara represented the interests of his mother and sister after the death of Jack, his father. He joined the club in 1964 as vice president and treasurer. In 1976, Tim and Wellington Mara had their first major disagreement: Wellington wanted to sign Larry Csonka and Tim did not. By the end of the 1978 season, the Giants had won only 74 of their last 212 games. On December 18, 1978, Robustelli resigned as director of operations and Tim and Wellington Mara could not agree on a successor. Wellington wanted to promote Bledsoe while Tim wanted to hire Dallas Cowboys personnel director Gil Brandt or Los Angeles Rams general manager Don Klosterman. After a 45-day stalemate, Commissioner Pete Rozelle intervened and a compromise candidate, Jan Van Duser, was chosen. However, Van Duser did not want the job. After their public dispute, Wellington and Tim Mara stopped talking to each other and the owner's box at Giants Stadium was divided by a partition. Neither side of the family had enough money to buy out the other one. Wellington Mara and his wife Ann Mara had 11 children. Chris Mara, Giants' senior vice president of player personnel, married Kathleen Rooney, a member of the family that owns the Pittsburgh Steelers.
