Thirston is an uncommon given name of American origin. It is derived from English surnames like Thompson, which are thought to be of Old Norse derivation, originally meaning 'son of Thorfinn'. The name was also found among early settlers in North America, suggesting it could have been brought over by Scandinavian immigrants or adapted by Americans of other backgrounds who were influenced by the Viking settlement period. Despite its historical roots, Thirston is not a name that has seen widespread usage and remains quite unique today.
The name Thirston was borne by six individuals who were born in the year 1921.
