Tanielu Tupu Kaitoa Siilata

It is with heavy hearts that we share the passing of our beloved Tanielu Tupu Kaitoa Siilata, who left us far too soon on March 12, 2026, just shy of his second birthday. Born on March 24, 2024, in Lehi, Utah, Tanu was a bright light in the lives of everyone he touched. Affectionately known as Tanu or Tupu for short, his infectious joy and curiosity captivated all who had the pleasure of knowing him.

Tanu was a spirited little boy whose laughter filled the air. His laugh was loud and infectious, the kind that made everyone turn to see the child giggling so joyfully that they couldn't help but smile and join in. He found joy in the simple things, from playing at the park to dancing and singing along to his favorite reggae and K-Pop tunes. With chopsticks in hand, he could often be found drumming out his own beats, bringing smiles to those around him. Tanu gave the best hugs and loved hugging and following his big brother, Kepa, every step of the way.

He shared a special bond with his Grandpa, Joseph Marks, who looked on with pride as Tanu explored and experienced the world. A family motto from Grandma Joanna Marks that we taught our Tanu was, "Us against the world."

His parents, Pupi Siilata and Liliana Kawena Marks, cherished every moment with their beautiful son, who was a constant reminder of love and happiness.

A viewing will be held on Thursday, March 19, from 6:00-8:00 PM at Anderson & Sons Mortuary in American Fork. An additional viewing will take place on the day of the services from 9:45-10:45 AM on Friday, March 20, at the same location. Funeral services will follow at 11:00 AM at Anderson & Sons Mortuary.

Following the service, we will lay Tanu to rest with love at his final resting place at Saratoga Springs Cemetery.

Tanu is survived by his loving parents, Pupi Siilata and Liliana Kawena Marks; his brother, Iokepa "Kepa" Siilata; his Grandpa and Grandma, Joseph and Joanna Marks, and Grandpa and Grandma, Tomai and Ailaoa Siilata; as well as many aunts, uncles, and cousins.

Though Tanu's time with us was brief, his spirit will forever resonate in the hearts of his family and friends. We invite you to join us in honoring his memory and celebrating the joy he brought to our lives.

Aloha 'oe to our Tanielu Tupu.
