When ever I get introduced with my full name "Palaniappan Palaniappan", the same question is asked to me.
I like to share it here, It seems to be same First name and Last Name of mine. I should start with the History from my Grand Father. My Grand Pa's name is also Palaniappan. And another one beauty was his Father In Law's name was also the same (Palaniappan).
When My Dad was born, my Grand ma kept her Father's Name.
When I was born, My Dad Kept his father name to myself.
Finally I became Palaniappan.
