Onnie is a gender-neutral given name of English origin, derived from the Scottish surname MacDonald. It is composed of two elements: 'Mac,' which means "son of" in Gaelic, and 'Donnchaidh,' an ancient Scottish name meaning "dark warrior." The name Onnie has gained popularity as a unisex given name in recent years, with its uniqueness making it appealing to parents seeking distinctive names for their children.
The name Onnie experienced fluctuating popularity throughout the years, with a notable peak during World War I. The highest number of births recorded was 26 in 1915 and 22 in 1916, coinciding with the war years. However, it's worth noting that the overall trend shows a decline in usage over time, with fewer than 10 births per year from 1972 onwards, and only five occurrences between 1988 and 2015 (assuming no Onnie births were recorded after 1988).
