Truby is an uncommon given name, believed to have originated as a variant of the Latin name Tubero, which means "bearing a tub-like shape." This could refer to someone who was sturdy or robust in appearance. The name Truby is not commonly found in popular baby name lists, making it quite distinctive and unique. It was used more frequently in the United States during the late 19th century but has since become quite rare. As a result, anyone named Truby today is likely to have a very individual moniker.
"Truby was quite popular among parents from the early 1920s to the late 1940s, with a slight dip in usage around 1929-1946."
