Meaning & origin

Rennie is a name with Scottish and English origins, first recorded in U.S. Social Security data in 1885, the same year it reached its peak usage. Despite that early peak, it has never entered the modern top 1000 ranks and has maintained a stable trajectory over the decades. The name's connection to the Scottish landscape and its use as a diminutive of Renata or Irene give it a versatile, gentle appeal. While no single state has shown a particular concentration of Rennies, the name has appeared sporadically across the country. Its long, quiet history makes it an understated choice for parents seeking a name with roots but without widespread modern use.

Rennie originated as a Scottish habitational surname from a place named with Gaelic *raonach* ('marshy land') or from a location called Rennie in Aberdeenshire. As a given name, it emerged in the 19th century, often used as a pet form of Renata (Latin 'reborn') or Irene (Greek 'peace'), or as a Scottish feminine diminutive. It has seen modest use in both the United Kingdom and the United States, with a historical lean toward females in recent decades.
