Re: meaning of my name ..Vitra
I tried searching for your name all over the place. From what I've seen. it's probably a varient of the name Victor, or Vitale. Victor means "conqueror", and Vitale means "vital"
I came to this conclusion this way: Your name is similar to Vitya, and other names that are varients of Victor.
VITYA: Russian. Pet form of VITALIY or VIKTOR
Vitaliy: Russian form of Vitalis (see VITALE).
Vitale: Italian form of the Late Latin name Vitalis, which was derived from Latin vitalis "of life, vital". Vitalis was the name of several early saints and martyrs.
Viktor: Russian form of Victor.
I found this is the comments for Victoria, since you didn't say whether your name is feminine or masculine.
"Vita is also a short/pet form of Victoria."
Also, your name is similar to:
Vitas: Latin. Alive, Vital
That's the best I can do. But, I'm not an expert anyway. :)
I also found this while I was searching:
VITRA:
Veridical Imaging of Transmissive and Reflective Artefacts
:D
Names are interesting. :)
