Teagon is of American origin, a modern coinage that gained popularity in the late 20th century. It's composed of the elements 'Tae', which may be a shortened form of names like Tate or Thaddeus, and 'on', possibly inspired by names ending in that syllable, such as Jonathan or Jonathan's diminutive Jonah.
The name Teagon has seen a resurgence in popularity between 2009 and 2018, with a total of 17 children born with this unique name over these years. While the number of births peaked at 7 in 2012, there were also notable spikes in 2009 and 2018, suggesting that Teagon continues to be an appealing choice for parents even outside of its peak popularity period.
