George Gavin Maclennan

George Gavin Maclennan, known to family and friends simply as Gavin, died in Houston, Texas, on July 15, 2026, at the age of 84.

Gavin was born in Sydney, Australia, on March 8, 1942, to George Gorton Maclennan, a blacksmith and owner of a steel mining business, and Helen Beattie Dunlop, a clothing designer. Between his father's practical craftsmanship and his mother's creative eye, he inherited a little of each. His childhood was spent between Australia, Singapore, Kuala Lumpur, and Scotland. While Gavin attended boarding school in Edinburgh, his parents continued living and working abroad. Along the way, he even picked up some Malay. It was an unusually international upbringing for its time, one that shaped his lifelong comfort with new places, new people, and new ideas.

One story from Gavin's youth offers a glimpse of a side of him that not everyone knew. At seventeen, he traveled to Paris in pursuit of a young woman he had fallen for. Whether the plan was well considered is another matter, but it revealed a quiet romantic streak that often lived beneath his practical exterior.

Curiosity was one of Gavin's defining qualities. He collected interests almost as readily as certificates. Over the years, he studied finance, real estate, public speaking, electrical systems, and technology through programs at the University of Houston, Oxford, Cambridge, the University of London, and elsewhere. His technical work included managing electronic equipment in hospitals, as well as contributing to the development of early automated teller machine technology. Even in the last years of his life, he was experimenting with artificial intelligence, still chasing whatever happened to catch his interest.

Gavin's professional life took several turns, beginning with technical and electrical work before later moving into real estate. In 1974, he married Barbara Sue Harris, and together with Barbara's brother, John Harris, they entered the real estate business. Beyond work, Gavin and Barbara built a life that included two children, Laurie and Stewart, forty years of marriage, and many trips to Scotland, Costa Rica, and Mexico before Barbara's death in 2014.

In 2016, Gavin married Sylvie Blaser, whom he had known for many years through mutual family friends. Their years together were filled with conversation, laughter, and many memorable dinners at home, courtesy of Sylvie—who usually found it easier to chase Gavin out of the kitchen than to let him help. They traveled to Scotland to visit Gavin's son and grandchildren and to France to spend time with Sylvie's family.

Gavin was drawn to understanding how things worked. He sailed, played tennis, painted, sang in the church choir, and played both the piano and the bagpipes throughout his life. He restored an antique clock that belonged to Sylvie, partly because he wanted to understand its mechanism and partly because he took quiet satisfaction in bringing something meaningful back to life for someone he cared about. He enjoyed carpentry, could repair almost anything mechanical, and rarely met a project he wasn't willing to dismantle first and figure out later. If something broke, Gavin generally considered it an invitation.

He had strong opinions, a dry wit, and a reputation for being careful with money—a characteristic his family never let him forget. Gavin wasn't always easy to know. Beneath a practical exterior and a sometimes blunt manner was a sensitive person whose feelings were more easily hurt than he often let on. His affection usually appeared in practical ways rather than sentimental ones: a cup of coffee waiting in the morning, an unexpected solution to a difficult problem, or his dog, Bonnie, carefully tucked beneath a blanket each night before bed.

Gavin is survived by his wife, Sylvie Maclennan; his daughter, Laurie Maclennan Jones, and granddaughters Abby and Zoe Salmon of Houston; his son, Stewart Wade Maclennan, and granddaughters Kathryn, Esther, Amber, Lorna, Annabelle, and Veronica of Scotland; Older Sister Mhoire Williams of Georgia; his brother-in-law, John Harris; his stepdaughter, Stephanie Wherry; and Bonnie.

Gavin's life crossed continents, careers, and interests, but curiosity remained the constant. He leaves behind enough stories to keep his family debating the details for years to come. He would probably have enjoyed having the last word. In the end, though, the stories belong to those who knew him—and they are better for having him in them.
