Well i see you got your answer already! sorry i couldn't respond any sooner, but i guess i was sleeping when you posted!
What
Lucille said about our naming system is correct, i've got my own example to that:
my full name is
Petronella Rosina, this name is on all my bankaccounts, passport and will be on my grave later, but my calling name is
Larissa ...if you look good you can see
Larissa out of
Petronella Rosina.....lol. I'm not a
Christian, but
Petronella Rosina is my Grandmother's full name, i'm named after her......
Well guess you got all your questions answered already!
