Clan Tweedie, originating from Scotland, has a history rooted in the region of Peeblesshire. The Tweedies were respected landowners and played a vital role in local governance.
One notable member of Clan Tweedie is John Tweedie, a renowned botanist who lived during the 19th century. John Tweedie embarked on several scientific expeditions to South America, where he collected and cataloged numerous plant specimens. His contributions to the field of botany greatly expanded the knowledge of South American flora, and his collections formed the foundation of several botanical gardens and institutions.
