Glennon is a name of Irish origin and means "from the fair-haired valley". It is believed to have originated from the old Gaelic word "glinn" which means "valley", combined with "dubh" meaning "dark-colored". However, there are some variations in the interpretation of its meaning.
The name Glennon was traditionally passed down through generations in Irish families. In Ireland, it was often used as a surname rather than a given name. The earliest records of the name date back to the 13th century where it appeared as O'Glinnin or O'Glennon.
Over time, Glennon has evolved and adapted. In some instances, it has been anglicized to Glenon, while in others, it has been used as a female given name rather than just a male surname. Today, Glennon is still relatively uncommon but can be found worldwide due to Irish immigration patterns over the centuries.
In terms of its popularity, Glennon has not featured prominently on baby naming lists. According to data from the Social Security Administration in the United States, it has never been among the top 1000 names for boys or girls since records began in 1879. Nevertheless, Glennon continues to be used by some families as a nod to their Irish heritage.
Overall, Glennon is an ancient and historic name with roots deeply embedded in Irish culture and history. Its unique meaning and relatively rare usage make it a distinctive choice for those looking for something different.
The name Glennon has been used consistently but not frequently in the United States over the past century. Between 1912 and 1995, there were a total of 1,244 births registered with the first name Glennon.
Looking at the year-by-year statistics, we can see that the popularity of the name Glennon fluctuated significantly throughout this period. The highest number of births occurred in 1926 and 1928, with 31 and 32 births respectively. However, there were also several years with only a handful of births registered, such as 1966 and 1972, where only five and six births were recorded respectively.
Interestingly, the use of the name Glennon seemed to decline after the 1950s. While there were still some years in the 1980s and 1990s with a reasonable number of births (such as 12 births in 1986), the overall trend was towards fewer births being registered with this name.
Overall, while Glennon may not have been one of the most popular names in the United States during this period, it was still used consistently enough to result in over a thousand births over the course of eight decades.
