An Irish-Gaelic girl's name meaning "young doe". Possibly made popular in the 1980's by a female character, Tegan Jovanka, from the British Sci-fi series "Doctor Who", resulting in several women from their teens to 20's with that name (as of 2007).

Irish Celtic name meaning "beautiful". Imagine a beautiful red haired blue eyed Irish girl. Gorgeous and fiery, this girl will break the boys hearts unintentionally with her inner and outer beauty. She will take care of herself with her strong will and stubborn red head ways.
Tegan is a girl you havent met yet, but long to. Tegan is correctly pronounced TEH-GUN or TAY-GUN, but is commonly mispronounced as TEE-GUN. Some prefer to pronounce it TEE-GUN, but that is incorrect traditionally.

Tegan identifies beautiful, cute girls who have a spark to them. They're often very flirty but also very caring. Often trusting too much of people who don't deserve it, and a history of getting hurt. Tegan's need to remember their close friends in time of need more often.
I wish I knew if I could trust Tegan, she has so many guys in her life and such a thick history.

Her eyes sparkle like Tegan's!
She acts like such a Tegan.

A person that is nice, she will brighten your day probably...... but she is also a sassafras and loves to lead the way. And no wonder her name means beautiful it practically describes her. The only down part she’ll yap your ear off.
You’re acting like a Tegan
