Jamie Murphy, 37, was rushed to hopsital after saying he had a headache and later collapsing.
His son, seven-week-old Frankie was also taken to the hospital to be christened at Salford Royal Hospital as his father's life faded.
According to The Sunday Mirror, father Jamie, from Benchill in Manchester, passed away 24 hours after suffering a brain bleed.
More than 50 of his family members were present for the Christening and Mr Murphy's family agreed to donate his organs to help others.
His heart, liver and kidneys saved three lives: "Even now he's still helping people," said his sister Steph.
The Mirror has reported that since his death, dozens of people have donated more than £4,600 to support baby Frankie and new mother Sarah.
