In process of searching name for my upcoming baby, I also tried to find the source of my name and my wife name.
Here they are.
My wife name from Italian name, taken from famous opera character in opera Il Don Giovanni. It was premiered by the Prague Italian opera at the Teatro di Praga (now called the Estates Theatre) on October 29, 1787. Donna Elvira is leading woman character with soprano voice. This a very famous opera story until now.
My name from India name taken from Sanskrit name, Nanda supposed to character from Sanskrit book, this a male name as head of cowherd man and also another name for Khrisna father name Nanda Maharaja.
I have no idea why (Pak Satar) my father put Mus in front of Nanda and became Musnanda. My name become unique then.
Some of my friend said that Nanda supposed to be a girl name, upps they are wrong.
