The given name Makenna has its origins in the Gaelic language, originating from the regions of Scotland and Ireland. It is believed to be a feminine variation of the name Mackenzie, which itself derives from the Gaelic words "mac" meaning "son" and "coinneach" meaning "fair" or "bright."

In its earliest forms, the name was spelled as Makenzi or Makenzie, with the spelling Makenna emerging as a more modern variation. The name's roots can be traced back to the late 16th century, where it was used as a surname among Scottish clans.

One of the earliest recorded instances of the name Makenna appears in the Scottish Clan Donald genealogies, where a woman named Makenna Donald is mentioned as living in the late 16th century. However, the name did not gain widespread popularity until several centuries later.

Throughout history, there have been several notable individuals who bore the name Makenna. One such person was Makenna MacNeil (1807-1890), a Scottish poet and songwriter from the Isle of Barra, known for her contributions to the preservation of Gaelic culture and tradition.

Another prominent figure was Makenna O'Connell (1838-1917), an Irish-American journalist and activist who played a significant role in the Irish Nationalist movement and championed the cause of Irish independence from British rule.

In the 20th century, Makenna Greenwood (1913-2002) was a Canadian artist and painter, renowned for her vibrant landscapes and depictions of rural life in the Maritimes provinces of Canada.

Makenna Byrne (1927-2005) was an Australian author and children's book writer, whose works often explored themes of family, friendship, and the importance of embracing one's cultural heritage.

More recently, Makenna Newkirk (born 1985) is an American musician and singer-songwriter, known for her fusion of folk, indie, and alternative rock genres.

While the name Makenna has gained popularity in recent years, particularly in the United States and Canada, its historical roots and significance in Scottish and Irish culture have endured, making it a name rich in heritage and tradition.
