Charles Sidney Johnston, 92, passed away peacefully on May 18, 2026. Sid was born on April 21, 1934, in Oklahoma, to Otis Sidney Johnston and Cleopatra Franklin Johnston.  He was raised in small-town alongside his siblings in a hardworking family rooted in faith, grit, fun, and common sense. He was a member of the Chickasaw Nation and carried his Oklahoma roots and country values with him for the rest of his life. Sid served in the United States Army from 1956 to 1958.

In 1972, Sid married the love of his life, Gloria. Born and raised in Brazil, Gloria was 18, he was 38, and from the moment they met at that small town in Brazil, that was it for both of them. Gloria liked to say that it was Serendipity: he was looking for oil and found gold in her (-:

Through every season of life, Gloria remained the only love of his life and his greatest companion. Their marriage lasted more than five decades and endured with loyalty, humor, stubbornness, and devotion.

Sid was a man of sayings, lessons, and routines. Family members can still hear him saying things like, “Put tools back where you found them,” “Don’t count your chickens before they hatch,” and “Don’t put all your eggs in one basket.” He believed in taking care of what you owned, doing things correctly the first time, and not making life harder than it had to be.

He enjoyed simple pleasures: a cold Brahma Chopp beer from Brazil, football, socializing, reading books, and keeping up with politics. His favorite song was Luckenbach, Texas, and those who knew him best like to believe he finally made it there, where there ain’t nobody feelin’ no pain.

Sid had a strong will with a great sense of humor. Even in his final days, at 92 years old and battling dementia, he was making the caregivers laugh; he still managed to prove the doctors wrong one last time and leave this world entirely on his own schedule.

In the 1960s, Sid began working as a mechanic on seismic vibration equipment used in oil exploration, helping crews search deep beneath the earth for oil reserves. It was hard, technical work that perfectly suited his hands-on nature, mechanical mind, and ability to fix just about anything put in front of him.

Sid traveled all over the world throughout his career with Western Geophysical, working in places across Asia, Africa, South America, and the Middle East. Sid spent time in Egypt, where he learned to play chess, a game he would later teach to his son Kevin at the age of seven. Like most things Sid taught, it came with both patience and strategy.

What started as a mechanic’s job eventually became a lifelong career. Through years of hard work, leadership, and earned respect, Sid rose through the ranks and ultimately became manager of a large seismic equipment shop in Alvin, Texas, overseeing operations and mentoring the people who worked alongside him.

Sid was preceded in death by his best friend and younger brother, Otis Ancel Johnston (May 7, 2026), and his two older sisters, Yvonne and Deahn.

Sid is survived by his loving wife, Gloria Garcia Johnston, and one of their twins, Kevin Garcia Johnston.  He was preceded in death by the other twin, his beloved daughter, Tannya Dantas Johnston (1981-2003). He also leaves behind his grandson Parker Dantas Johnston (Kevin’s son), whose presence brought him great pride and joy.

Sid had three children from a previous marriage – Therese Stone (son Justin [deceased]), Roger Johnston (son Chad), and Carla Ford (daughters Kayla and Candice).

The family would like to thank the caregivers, nurses, and doctors who cared for Sid during the final stages of his life. Their compassion, patience, and kindness brought comfort to Sid and his family during a difficult time.

In true Sid fashion, he likely would not want too much fuss made over all of this. He would probably just remind everyone to put things back where they found them, keep their word, and enjoy a cold beer while they still can.
