Answer by taking a quote from the following article:

John Constantine Unitas was born in Pittsburgh in 1933 to Francis J. Unitas and Helen Superfisky, who both were of Lithuanian descent; he grew up in the Mount Washington neighborhood. When Johnny was five years old, his father died of cardiovascular renal disease complicated by pneumonia, leaving the young boy to be raised by his mother, who worked two jobs to support the family. His surname was a result of a phonetic transliteration of a common Lithuanian last name Jonaitis. Attending St. Justin's High School in Pittsburgh, Unitas played halfback and quarterback.

In 1971, Unitas split playing time with Morrall, throwing only three touchdown passes. He started both playoff games, a win over the Cleveland Browns that sent the Colts to the AFC Championship game against the Miami Dolphins, which they lost by a score of 21-0. Unitas threw three interceptions in the game, one of which was returned for a touchdown by safety Dick Anderson.  The 1972 season saw the Colts declining into mediocrity. After losing the season opener, Unitas was involved in the second and final regular season head-to-head meeting with "Broadway" Joe Namath. The first was in 1970 (won by the Colts, 29-22). The last meeting was a memorable one, which took place on September 24, 1972, at Memorial Stadium. Unitas threw for 376 yards and three touchdowns, but Namath upstaged him again, bombing the Colts for 496 yards and six touchdowns in a 44-34 Jets victory - their first over Baltimore since the 1970 merger. After losing four of their first five games, the Colts fired head coach Don McCafferty, and benched Unitas.  One of the more memorable moments in football history came on Unitas' last game in a Colts uniform at Memorial Stadium, in a game against the Buffalo Bills. Unitas was not the starter for this game, but the Colts were blowing the Bills out by a score of 28-0 behind Marty Domres; Unitas entered the game due to the fans chanting, "We want Unitas!!!", and a plan devised by head coach John Sandusky to convince Unitas that the starting quarterback was injured. Unitas came onto the field, and threw two passes, one of which was a long touchdown to wide receiver Eddie Hinton which would be his last pass as a Colt. The Colts won the game by the score of 35-7.

Did Unitas have a family?
