Daniel Jonathan D'Andrea, 77, of Lincoln, CA, passed away on August 24, 2025, surrounded by his loving family. Daniel (Dan to his friends) was born on May 7, 1948, in Alleghany County, PA, the son of William and Mary (née Nolfi) Andrews.

Daniel graduated from Fremont High School in 1966 and then enjoyed a year of study at De Anza College. After building skills and experience at various locations, he spent 18 years as a Maintenance Engineer with Amdahl. He then devoted over twenty years to the loving care of his mother, Mary.

Daniel was a member of Calvary Community Church of Almaden for over twenty years and LifeChurch in San Jose for nearly ten years where he served as usher.

Daniel loved animals, especially his dogs Petie, Rusty, Heidi, and Lancelot. He was an avid sports fan (go 49ers!) and member of the NRA. Above all, he loved his family.

Remaining to cherish Daniel's memory are his siblings William and Carrie, Marilyn and Matt, and Silia and Mark; his nieces and nephews David and Rebecca, Angela and Jon, Lauren and Joel, Jonathan and Kelsea, Jacki, Kim, Gregory, and Jessica and Josiah; great-nieces and nephews Fiona, Eva, Rowan, Logan, Sierra, Declan, Adam, Philip, Hailey, Noah, Jonah, Gabriella, Michelle, Everly, Asher, Marshall, and William; and many relatives and friends. (And yes, he remembered everyone's name.)

Preceding Daniel in death are his parents William and Mary, his brothers Patsy and Robert, and many loved ones.

Visitation and memorial services will be held at 10:30am on Saturday, September 6, 2025, at Spangler Mortuary in Sunnyvale, CA, with Pastor Doug Buron officiating. Internment will be at Gates of Heaven cemetery in Los Altos, CA.
