Please resist the urge to call me by my first name. Now that we got this out of the way, here is some explanation.
Not everyone in the world use the same system of nomenclature! Is it such a surprise? I can't think of anything that is done the same way the world over (no, not even McDonald's burgers!). I happen to hail from a place that has a naming system which is different from the western norm. My given name is written last (i.e. the "last name"). We don't have a notion of family names. I am called "Asokan" on informal occasions as well. The "N." stands for my first name, "Nadarajah". In very legal circumstances (e.g. in my passport or in a contract), I use this first name in full as well. My first name is a patronymic: "Nadarajah" is my father's last name. My full name, Nadarajah Asokan, essentially means "Nadarajah's son Asokan." So, this is why I don't want to be called "Nadarajah".
As you can imagine, having a "non-standard" name, I usually end up tripping the personnel and IT administrative systems that I have had to deal with in North America and Europe. Most have been flexible enough to adapt their systems to suit my wishes. Those administrators and software engineers who hard-code specific (western) naming conventions in designing their systems have yet to learn the "mechanism, not policy" design principle.
My name means "he who is without sorrow". It is derived from the sanskrit word "asoka". There was a famous Indian emperor who was probably the first person to sport this name. The wheel in the Indian national flag is called the "ashoka chakra." The four-lion pillar erected by King Asoka is also used as a national emblem of India.
A village in New York is called Ashokan. I don't know how it came about. The village is now largely under the Ashokan reservior which is said to supply water to about 50% of NYC residents. There is a tune called the "Ashokan Farewell" composed by Jay Unger. It was later used as the theme song in the PBS television series The Civil War .
"Nadarajah" is a variation of the name "Nataraja." It is a manifestation of Lord Shiva as he dances his dance at the end of the universe!
If you think that wasn't complicated enough for you, ask me about the pronounciation of my name -- that is a whole new can of worms!
