Thaddeus John Jaje, born on September 24, 1942, in Philadelphia, PA, passed away on March 23, 2026, in Saint Inigoes, MD. He was a devoted father, a cherished friend, and a beloved member of his community.

Thaddeus received his bachelor's degree from American University and built a successful career as a computer data analyst with Unisys (Sperry-Univac) where he worked diligently as a contractor for over 30 years before retiring in 2010. His passion for technology and problem-solving was evident in both his professional life and personal interests, and his contributions in the field left a lasting impact on those around him.

On February 8, 1975, in St. Mary's Catholic Church, Landover Hills, MD, Thaddeus married the late Joan Jaje, and whom preceded him in death on September 29, 2013. Together, they created a home and shared countless memories. Thaddeus was a proud father to his son and stepchildren who will carry on his legacy with love and devotion. Thaddeus is survived by his son Matthew Jaje and wife Jennifer of Wilmington, DE, his stepdaughter Deborah Clark and husband Joseph of Queen Anne, MD, and his stepdaughter Donna Burriss and husband Thomas of AL. He was preceded in death by his brother Stanley Jaje, stepson Darby McNeill, and stepdaughter Dorrine McNeill.


A Graveside Service will be held in his honor at Immaculate Heart of Mary Catholic Cemetery in Lexington Park, MD, on March 30, 2026, at 10:00 AM. Pallbearers will be Matt Jaje, Simon Jaje, Elliot Jaje, and Rick Cox. Family and friends are invited to gather to pay their respects and to celebrate the life of Thaddeus John Jaje, whose spirit will continue to shine brightly in the hearts of those he loved.

In lieu of flowers, the family requests that donations be made to a local charity in Thaddeus's name, a fitting tribute to a man who always believed in giving back. Thaddeus will be laid to rest, but his memory will live on in the stories we share and the love we carry in our hearts.
