Tristyn - Polish version of my Celtic name?

My name is Tristyn, and my French friends spell it Tristane or Tristène to indicate that I'm a female, and my Spanish friends spell it Tristán. What is the Polish equivalent?

Tycjan.....you say it like 'tits-jan'
That's how I remember it, jan has tits, so titsjan/tycjan

Tristan.

Tristan is Wagnerian isn't it? As in Tristan and Isolde.

Celtic

Tristan was Cornish, herself was Irish.

I'd never heard of this legend until a film was released a few years ago, I had heard about what I may have been based on though:

Is Tycjan feminine as well? It counts in some languages.

Tycjan is a male name that is a diminutive form of the name Titus, of Ancient Roman, and probably pre-Roman origin. In English, it's spelt Titian. It is completely unrelated to the Celtic name Tristan. Any similarity is purely coincidental and has no significance whatsoever to your original question.

The feminine form is Tycjana.
