Since I am adopted I have two names. One is Mariluz (given to me by my birthmother) and the other official name is Esther though I use Escobana as a nickname for Hubpages.
Since I live in Spain and since I feel closer to my roots here than in Holland, I let people choose which name they like. Some call me Mariluz but most of my friends call me Esther.
I would not change my name but using the name Mariluz feels symbolic to me.
