Trenton E. O’Brien

Haddam, East Haven


Trenton E. O’Brien, 7, of Haddam and East Haven, left this life peacefully in his father’s loving arms in the early morning hours of Jan. 10. He was born in New Haven on Nov. 14, 2012. His father Timothy M. O’Brien and parent Marissa L. O’Brien currently reside in East Haddam, having recently moved from East Haven.

Trenton was in the second grade at Momauguin School. He was a great kid who loved to goof around, was a fanatic for Pokémon and Pokémon Go, loved video games, especially Minecraft, enjoyed assembling Lego models, reading comic books, seeing super hero movies, especially Spider-Man, and loved to draw. Even from an early age, he enjoyed all types of food. Some of his favorites were shrimp scampi and tacos.

Besides Tim and Marissa, Trenton leaves a brother, Sebastian Onofrio of West Haven; his maternal grandparents John Onofrio and Fran Gambardella of North Haven; paternal grandparent Stacey Venn of East Haddam; step-grandmother Hannah Marro of West Haven; and several aunts and uncles, Joseph and Natasha Onofrio of West Haven, Jessica O’Brien of Seymour, Matthew and Kristin O’Brien of Madison, Erik Londono of West Haven, Nikki Prete of North Haven, Amanda O’Brien of New Hampshire, Christa Marro of West Haven, and Daniel Bednarsky of Oxford. Lastly, he leaves his companion, Beaver the cat.

Trenton’s family would like to extend a heartfelt appreciation to so many who showed support and love for their entire family during this extremely difficult time. First, they want to thank his caregivers; the doctors at Yale Children’s Hospital; nurses both at the hospital and then the hospice staff who cared for him while he was home; the entire community of East Haven; his school family at Momauguin School; the Fire Department for making him an honorary firefighter for Volunteer Company 6; the Police Department for their visit and gifts; Mayor Joseph Carfora for making Jan. 2 “Trenton O’Brien Day”; and countless others who gave so generously their time and money for the various fundraisers. It will never be forgotten.

A Memorial Mass was celebrated on Jan. 20 in the parish of St. Pio of Pietrelcina at St. Vincent de Paul Church, Taylor Avenue. Calling hours took place on Jan. 18 at the East Haven Memorial Longobardi–Brennan Funeral Home, 425 Main St., East Haven, 203-467-1708. Burial was private. Memorial contributions may be made to DIPG “The cure starts now,” 10280 Chester Rd., Cincinnati, OH 45215. Please visit Trenton’s memorial page at and sign his guest book.
