Females in the Fellowship

[Lalaith]

I dont think any other elven woman went on dangerous quest or journeys with exceptions of going to help or be with people they love, or so they wouldnt die.

Eleven maiden Earwen, I would point you to Galadriel, who embarked on the highly perilous journery from Valinor with the sons of Feanor because she wanted to rule over a kingdom of her own. And to Aredhel, who left her brother's safe kingdom of Gondolin purely because she felt enclosed and wanted to ride free in the forests.
