Sonnie, of Hebrew origin, is derived from the name Solomon, which means 'peace'. It is often considered a diminutive form of the same name and has been used independently in recent years. The name gained popularity in the United States during the mid-20th century but has since become more widely recognized globally. Its unique spelling sets it apart from other nicknames or shortened forms of Solomon, making it a distinctive choice for parents seeking an uncommon yet meaningful name for their child.
The name Sonnie experienced varied popularity over the decades, with a notable rise from the late 1970s to the mid-1980s, peaking at 23 births in 1989. However, it has since become less common, with fewer than 10 births per year since 2006. The most recent data shows a slight uptick in popularity, with 20 births recorded in 2023.
